Replace the for loop by a ternary operator whose condition is an AND bitmask against the priv->basic_rates variable. The purpose of the for loop was to check if any of bits from RATE_54M to RATE_6M was set, but it's not necessary to check every individual bit. The same result can be achieved using only one single mask which comprises all the commented bits. This way avoid the iteration over an unnecessary for loop. Also change the return type to bool because it's the type that this function returns. Signed-off-by:

gasket_sysfs_register_store() invokes get_mapping(), which returns a reference of the specified gasket_sysfs_mapping object to "mapping" with increased refcnt. When gasket_sysfs_register_store() returns, local variable "mapping" becomes invalid, so the refcount should be decreased to keep refcount balanced. The reference counting issue happens in one exception handling path of gasket_sysfs_register_store(). When gasket_dev is NULL, the function forgets to decrease the refcnt increased by get_mapping(), causing a refcnt leak. Fix this issue by calling put_mapping() when gasket_dev is NULL. Signed-off-by:

In wfx_remove_interface(), the current code differentiate AP and Station cases. However, it is not necessary. In all cases, the only important thing is the call to hif_reset(). We can use the same code to support all cases. Signed-off-by:

The callers of wfx_do_unjoin() already take care of vif state. Therefore, it is not necessary to take care of the status of the interface. Signed-off-by:

In former code (before the inclusion of the driver in mainline kernel), hif_join() could run asynchronously. When a join request was in progress, it was forbidden to launch hif_scan(). Now, hif_join() is always run synchronously. There is no more reasons to keep a protection against this case. Signed-off-by:

The structure hif_req_set_bss_params come from hardware API. It is not intended to be manipulated in upper layers of the driver. In add, current code for hif_req_set_bss_params() is too dumb. It should pack data with hardware representation instead of leaving all work to the caller. Signed-off-by:

Current code skip some configuration during joining an IBSS network. Indeed, it seems that this configuration is not used in IBSS. However, it would be harmless to set them. In add, we would prefer to keep association processes for ad-hoc and managed networks the closest as possible. It also ensures the values of internal parameters of the firmware. Therefore, apply them unconditionally. Signed-off-by:

Currently, events from firmware are handled in a work queue with a complex event queue mechanism. It is probably overkill since there is only two events to handle: bss_loss and CQM events. Handling these events synchronously is sufficient. Signed-off-by:

Since wfx_bss_params_work() does not exist anymore, there is no more reason to keep a copy of bss_params in struct wfx_dev. A local instance in wfx_join_finalize() is sufficient. Signed-off-by:

The firmware is able to filter beacons and send a notification if one or multiple beacons are not received. Note that it send this notification only once. Only if it receive beacons gain, it send a new notification. Currently, the driver handle the connection loss itself (see wfx_cqm_bssloss_sm()). It send null frames and watch the answers. This patch fixes all this mess: - settle firmware to send a notification on the first beacon loss - call ieee80211_beacon_loss() and let mac80211 handle all the process - since we do have notification for each beacon loss, add a period task that call ieee80211_beacon_loss() until we receive "REGAIN" notification. Thus, we can drop the ugly wfx_cqm_bssloss_sm() and wfx_bss_params_work(). Signed-off-by: -

Merge tag 'iio-for-5.8a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: First set of new IIO device support, features and cleanup for the 5.8 cycle Usual mix of new drivers, new support in old drivers and lots of minor cleanup. Yaml conversions also continue to trickle in (plenty more to go!) New device support * ad7476 - Add ad7091 support (ID only) * ad9467 - New driver for this 200/250 MSPS adi-axi-adc and SPI attached ADC. * adi-axi-adc - New driver to support ADIs generic AXI ADC IP core, used to provide high speed interfaces to ADCs (JESD204B/C or parallel interfaces). Usually paired with a device using a slow configuration interface (spi etc) Includes DT bindings and some fixes for fpga headers. * bmg160 - Add support for BMI088 (ID only) * max1241 - New driver for this ADC. * st_sensors - Add support for LIS2HH12 accelerometer * sx9310 - New driver supporting sx9310 and sx9311 proximity sensors. Yaml DT binding conversions * rockchip-saradc (including adding some missing parts) * stm32-dac * tsl2563 * vcnl4000 Features * st_lsm6dsx - Add LIS3MDL as a possible sensor hub device. * vcnl4000 - Add new concept of near level (from DT) to provide to userspace which often needs to have some calibrated concept of 'near'. Cleanups, minor fixes etc. * core - Use snprintf for functions where strings are built and there is potential for overflow. - Correct docs to indicate mlock should not be used directly by drivers. - Fix up accidental dropping of a patch to use bitmap_zalloc. - Stop allowing enabling of buffers with no channels enabled. - Drop unused 'stufftoread' from iio_buffer. - Drop scan_el_attrs form iio_buffer as unused. - Reorder sanity checks in __iio_device_register to fail earlier. - Drop all the devm_ runregister / free functions from IIO as they were never used and encourage poor design. * dma-buffer - Tidy up includes. * dma-engine-buffer - Provide dev-managed allocator. - Fix an issue with printing a size_t * cross subsystem (kxsd9, bmg160, mpu3050, bmi160, mpu6050, bmc150) - Replace some unnecessary casts of error ptrs and whilst there. use the %pe printf parameter to print them in a more useful fashion. * cross subsystem - Drop casts in calls to regmap_bulk_read as they make no sense. - Use devm_platform_ioremap_resource to reduce boilerplate. - Fix typos in Analog Devices. * counters/104-quad - Add Syed Nayyar Waris as an additional maintainer. * ad7476 - Generate CONVST signal internally rather than requiring external trigger. Add sysfs read back as can now do so. - use devm_add_action_or_reset to tidy up error and remove handling. * ad7793 - Switch to read_avail from explicit attribute. Mostly done to avoid confusing people with a - sign (without surounding spaces) that was correct but checkpatch didn't like. * adis library - Add missing newlines at end of error messages. * adis16400 - Use DEFINE_DEBUGS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTR. * adis16460 - Use DEFINE_DEBUGS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTR. * ad_sigma_delta - Move some channel definitions into individual drivers to avoid having to deal with complex options. * ak8974 - Silence an error on deffered probe. * bmp280 - Harden against IRQ before registration. - Convert to read_avail instead of opencoding the equivalent. - Explicitly mark GPIO as optional. - Cleanup casts. - Remove line breaks from strings. * htts221 - Replace direct access to platform_data with dev_get_platdata(). - Use device properties rather than device tree ones to allow ACPI probing. - Casting cleanups. * intel_mrfld_adc - Don't use unaligned accessor for aligned data. * isl29125 - Reorder buer pre and post hooks to allow for coming core rework. * ltc2983 - Remove comp to bool. * max1363 - Stop using mlock from the iio_dev directly in favour of a local lock with clearly defined scope. * max30100 - Use generic device properties to allow ACPI probe. * mpu6050 - Convert to i2c_new_client_device. - Add debugfs register access. * st_lsm6dsx - Provide means of configuring full scale on slave device if supported. - Drop include of st_sensors header to get one value. Its not otherwise used by this driver. * st-sensors - Replace direct access to platform_data with dev_get_platdata(). - Casting cleanups. - Avoid splitting strings. * st_uvis25 - Casting cleanups. * tsl2563 - Typo fix. * tsl2772 - scnprintf in a non obvious string building usecase. Note also 'fixes' a wrong calculation of remaining space that couldn't actually cause any trouble as there was lots of room. * xilinx-xadc - Fix Lars-Peter spelling his own name wrong :) + additional typos. * tag 'iio-for-5.8a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (101 commits) iio: magnetometer: ak8974: Silence deferred-probe error Documentation: ABI: document IIO in_proximity_nearlevel file iio: vcnl4000: Export near level property for proximity sensor dt-bindings: iio: light: vcnl4000: Add proximity-near-level dt-bindings: iio: Introduce common properties for iio sensors dt-bindings: iio: vcnl4000: convert bindings to YAML format iio: Fix misspellings of "Analog Devices" iio: light: isl29125: fix iio_triggered_buffer_{predisable,postenable} positions iio: adc: fsl-imx25-gcq: Use devm_platform_ioremap_resource iio: adc: at91-adc: Use devm_platform_ioremap_resource iio: adc: sun4i-gpadc-iio: Use devm_platform_ioremap_resource iio:light:ltr501: Drop unnecessary cast of parameter in regmap_bulk_read iio:magn:mmc35240: Drop unnecessary casts of val parameter in regmap_bulk* iio:imu:mpu6050: Tidy up parameters to regmap_bulk functions. iio:chemical:bme680: Tidy up parameters to regmap_bulk_read iio:chemical:atlas-sensor: Drop unnecessary explicit casts in regmap_bulk_read calls iio:accel:mxc4005: Drop unnecessary explicit casts in regmap_bulk_read calls iio: imu: st_lsm6dsx: drop huge include in sensor-hub driver iio: buffer: drop devm_iio_kfifo_free() API call iio: buffer: drop devm_iio_hw_consumer_free() API call ...

The iio_triggered_buffer_{predisable,postenable} functions attach/detach the poll functions. For the predisable hook, the disable code should occur before detaching the poll func, and for the postenable hook, the poll func should be attached before the enable code. This change reworks the predisable/postenable hooks so that the pollfunc is attached/detached in the correct position. It also balances the calls a bit, by grouping the preenable and the iio_triggered_buffer_postenable() into a single isl29125_buffer_postenable() function. Signed-off-by: -
