One of a class of bugs pointed out by Lars in a recent review. iio_push_to_buffers_with_timestamp assumes the buffer used is aligned to the size of the timestamp (8 bytes). This is not guaranteed in this driver which uses an array of smaller elements on the stack. Fixes: 232e0f6d ("iio: chemical: add support for Sensirion SPS30 sensor") Reported-by:

A wrong error message is printed out currently, like on STM32MP15: - stm32-adc-core 48003000.adc: IRQ index 2 not found. This is seen since commit 7723f4c5 ("driver core: platform: Add an error message to platform_get_irq*()"). The STM32 ADC core driver wrongly requests up to 3 interrupt lines. It should request only the necessary IRQs, based on the compatible: - stm32f4/h7 ADCs share a common interrupt - stm32mp1, has one interrupt line per ADC. So add the number of required interrupts to the compatible data. Fixes: d58c67d1 ("iio: adc: stm32-adc: add support for STM32MP1") Signed-off-by:

The light sensor needs the regulators to be enabled which means the runtime PM needs to be on. This only happened when the proximity part of the chip was enabled. As fallout from this change, only report changes to the prox state in the interrupt handler when it is explicitly enabled.

Since there will be some changes to how iio_priv_to_dev() is implemented, it could be that the helper becomes a bit slower, as it will be hidden away in the IIO core. But even without that rework, this looks like it can pass the 'indio_dev' object to ping_read() and obtain the state struct via iio_priv() which is a preferred practice than going back-n-forth (getting the state-struct, then using iio_priv_to_dev() to get the indio_dev object back).

Proximity sensor driver based on light/vcnl4000.c code. For now supports only the single on-demand measurement. The VCNL3020 is a fully integrated proximity sensor. Fully integrated means that the infrared emitter is included in the package. It has 16-bit resolution. It includes a signal processing IC and features standard I2C communication interface. It features an interrupt function. Datasheet: http://www.vishay.com/docs/84150/vcnl3020.pdfSigned-off-by:

Currently the driver only exposes the raw counts. As we have the regulator voltage and the maximum value (stored in the data mask), we can trivially produce a scaling fraction of voltage / max value. This assumes that the regulator voltage is in fact the max voltage, which appears to be the case for all mainline dts and cross referenced with the public Exynos4412 and S5PV210 datasheets.

It is clear that we transition to INDIO_DIRECT_MODE when disabling the buffer(s) and it is also clear that we transition from INDIO_DIRECT_MODE when enabling the buffer(s). So leaving the currentmode field INDIO_DIRECT_MODE until after the preenable() callback and updating it to INDIO_DIRECT_MODE before the postdisable() callback doesn't add additional value. On the other hand some drivers will need to perform different actions depending on which mode the device is going to operate in/was operating in. Moving the update of currentmode before preenable() and after postdisable() enables us to have drivers which perform mode dependent actions in those callbacks. Note, was originally not intended as such, but fixes an issue introduced in the at91-sama5d2 adc driver. Signed-off-by:

Jonathan Bakker authored
The bma023 chip is similar enough to the bma180 and bma25x that the same driver can support all of them. The biggest differences are the lack of a temperature channel and no low power but still working mode. The bma150 is a close relative of the bma023, but it does have a temperature channel so support is not added for it. Reviewed-by:

When a station is removed, the driver check that all the Tx frames were correctly sent. However, the station can be removed before all the Tx frames were acknowledged and a false positive warning can be emitted. The previous commit has added a trace when driver received an acknowledge for a non-existent station. It appear that these events are perfectly correlated and there is no leak. Now, the subject is perfectly understood. Remove the warning. Just keep a debug trace in case we have any doubt in the future. In the past, the subject has already been discussed here: https://lore.kernel.org/driverdev-devel/6287924.ghGFUMk3OD@pc-42/ Fixes: 4bbc6a3e ("staging: wfx: make warning about pending frame less scary") Signed-off-by:

The function wfx_tx_flush() wait for there is no more queued frames in hardware queue. Then, for the sanity, it checks that there is no more pending frame on any AC queue. However, there is a race here. It may happens that hardware queues are empty, but the counters of the AC queues are not yet updated. So, it may produce false-positive warning. The easiest way to solve the problem is just to remove the sanity check. Signed-off-by:

When multiple vif are in use (= one access point and one station), and when the channels are different, it is necessary to enable power save on station. The firmware check that steps are done in the correct order: - AP can't start if PS is not enable on the station - PS can't set on the station before the association has finished (= before the call set_bss_params) Obviously, in add, when one of the interface disappears, it is necessary to restore the power save status. wfx_update_pm() is able to set the correct PS configuration. But it has to be called at the right time: 1. before hif_start(), but after the channel configuration is known 2. after hif_set_bss_params() 3. after hif_reset() Therefore, the call to wfx_update_pm() from wfx_add_interface() is too early to address 1. The call after hif_set_bss_params() already exists. For the symmetry, the call from wfx_remove_interface() (that handle 3.) is also relocated. Signed-off-by: -
Jérôme Pouiller authored
The device disallows to start a scan request between hif_join() and hif_set_bss_params(). The driver is not protected against that. The worst case happens when association is aborted and hif_set_bss_params() never happens. mac80211 would never ask for scan during the association process. So, this patch just aborts the association in progress when scan is requested. Signed-off-by:
