The commit 473d12f7 ("iio: hid-sensor-attributes: Convert to use int_pow()") converted to use generic int_pow() helper. Though, the generic one returns 64-bit value and, in cases when it is used as divisor, it compels 64-bit division from compiler. In order to fix this, introduce a temporary 32-bit variable to hold the result of int_pow() and use it as divisor afterwards. In couple of cases, replace int_pow() with a predefined unit factors for time and frequency. Fixes: 473d12f7 ("iio: hid-sensor-attributes: Convert to use int_pow()") Reported-by:

As Christoph said [1], "I'd much prefer to just use read_cache_page_gfp, and live with the fact that this allocates bufferheads behind you for now. I'll try to speed up my attempts to get rid of the buffer heads on the block device mapping instead. " This simplifies the code a lot and a minor thing is "no REQ_META (e.g. for blktrace) on metadata at all..." [1] https://lore.kernel.org/r/20190903153704.GA2201@infradead.org/Reported-by:

As Christoph said [1], "This seems to be your only direct use of buffer heads, which while not deprecated are a bit of an ugly step child. So if you can easily avoid creating a buffer_head dependency in a new filesystem I think you should avoid it. " [1] https://lore.kernel.org/r/20190902125109.GA9826@infradead.org/Reported-by:

As Christoph said [1], "vm_map_ram is supposed to generally behave better. So if it doesn't please report that that to the arch maintainer and linux-mm so that they can look into the issue. Having user make choices of deep down kernel internals is just a horrible interface. Please talk to maintainers of other bits of the kernel if you see issues and / or need enhancements.

Merge tag 'iio-for-5.4b-take3' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Second set of new device support, cleanups and features for IIO in the 5.4 cycle Revised pull request to fix up a missing Signed-off-by and roll in a fix in the lsm9ds1 support after I broke it when applying. Revised again because the fix changed a hash meaning a fix that previously followed it now had the wrong fixes tag. A few fixes in here that could have gone a faster path but aren't quite worth the rush for 5.3. New device support * ad7606 - Support the ad7606b which adds a software controlled mode alongside the pin controlled only approach of the ad7606. Including dt-bindings. * lsm6dsx - Add support for the gyro and accelerometer part of the lsm9ds1 which is a compound device also including a magnetometer (st_sensors driver). Includes bindings and precursor rework of the driver. Features * ad7192 - Add support for low pass filter control. - DT binding docs. Cleanups and minor fixes * MAINTAINERS - Fix a typo in a path. - Add entry for ad7606 * ad5380 - Fix a failure to dereference a pointer before atempting to assign the value. * ad7192 - Drop platform data as not used in mainline and we now have full DT bindings. * ad7606 - YAML conversion for dt-bindings. * adis16240 - Rework write_raw to make it more readable using GENMASK. * adis16460 - Fix and issue with an unsigned variable holding potential negatives. * cros_ec - Fix missing default of calibration vector so that we get 'something' before calibration is complete on a given axis. * hid-sensors - Use int_pow instead of opencoding. * isl29501 - rename dt-binding docs to include renesas inline with other renesas parts and general current convention. * kxcjk1013 - Improve comments on the 'unusual' ACPI ids used to identify which sensor is which in certain laptops. * lsm6dsx - Add one bit to the fifo status masks for a number of parts. - Drop a reserved entry from the sensitivity values to tidy up interface. - Use core conversion macro from G to m/s^2 for lsm9ds1 to make it easier to relate to the datasheet and consistent with other parts supported. * max1027 - Use device managed APIs to avoid manual error handling and cleanup. * rfd77402 - Typo in Kconfig help. * sc27xx - Switch to polling mode from interrupts as interrupt handling typically to slow for very short sleeps. * st-sensors - Fix some missing selects for regmap. * tools - Add a .gitignore containing the binary outputs. * tag 'iio-for-5.4b-take3' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (27 commits) iio: imu: st_lsm6dsx: rely on IIO_G_TO_M_S_2 for gain definition for LSM9DS1 iio: imu: st_lsm6dsx: remove invalid gain value for LSM9DS1 iio: cros_ec: set calibscale for 3d MEMS to unit vector iio: dac: ad5380: fix incorrect assignment to val iio: imu: st_lsm6dsx: Fix FIFO diff mask for tagged fifo dt-bindings: iio: imu: st_lsm6dsx: add lsm9ds1 device bindings iio: imu: st_lsm6dsx: add support for accel/gyro unit of lsm9ds1 iio: imu: st_lsm6dsx: move register definitions to sensor_settings struct iio: imu: st_lsm6dsx: introduce update_fifo function pointer dt-bindings: iio: light: isl29501: Rename bindings documentation file Kconfig: Fix the reference to the RFD77402 ToF sensor in the 'help' section iio: st_sensors: Fix build error dt-bindings: iio: adc: Add AD7606B ADC documentation dt-bindings: iio: adc: Migrate AD7606 documentation to yaml MAINTAINERS: Add Beniamin Bia for AD7606 driver iio: adc: ad7606: Add support for AD7606B ADC tools: iio: add .gitignore iio: adc: sc27xx: Change to polling mode to read data iio: hid-sensor-attributes: Convert to use int_pow() iio: adc: max1027: Use device-managed APIs ...
