Jonathan writes: IIO: 2nd set of fixes for the 7.0 cycle Usual mixed bag of fixes for recent code and much older issues that have surfaced. Biggest group are continued resolution of IRQF_ONE_SHOT being used incorrectly (which now triggers a warning) adi,ad4062 - Replace IRQF_ONESHOT (as no threaded handler) with IRQF_NO_THREAD as the caller makes use of iio_trigger_poll() which cannot run from a thread. adi,ade9000 - Move mutex_init() earlier to ensure it is available if spurious IRQ occurs. adi,adis16550 - Fix swapped gyro and accel filter functions. adi,adxl3380 - Fix some bit manipulation that was always resulting in 0. - Fix incorrect register map for calibbias on the active power channel. - Fix returning IRQF_HANDLED from a function that should return 0 or -ERRNO. aspeed,adc - Clear a reference voltage bit that might be set prior to driver load. bosch,bno055 - Off by one channel buffer sizing. Benine due to padding prior to the subsequent timestamp. hid-sensors - A more complex fix to IRQF_ONESHOT warning as this driver had a trigger that was never actually used but the ABI that exposed had to be maintained to avoid regressions. hid-sensors-rotation - An obscure buffer alignment case that applies to quaternions only was recently broken resulting in writes beyond the end of the channel buffer. Add a new core macro and apply it in this driver to make it very clear what was going on. honeywell,abp2030pa - Remove meaningless IRQF_ONESHOT from a non threaded IRQ handler. Warning fix only. invense,mpu3050 - Fix token passed to free_irq() to match the one used at setup. - Fix an irq resource leak in error path. - Reorder probe so that userspace interfaces are exposed only after everything else has finished. - Reorder remove slightly to cleanup the buffer only after irq removed ensuring reverse of probe sequence. microchip,mcp47feb02 - Fix use of mutex before it was initialized by not performing unnecessary lock that was early enough in probe that all code was serial. st,lsm6dsx - Ensure that FIFO ODR is only controllable for accel and gyro channels avoiding incorrect register accesses. - Restrict separation of buffer sampling from main sampling rate to accelerometer. It is only useful for running event detection faster than the fifo and the only events are on the accelerometer. ti,ads1018 - Fix overflow of u8 which wasn't big enough to store max data rate value. ti,ads1119: - Fix unbalanced pm in an error path. - IRQF_ONESHOT (as no threaded handler) replaced with IRQF_NO_THREAD (needed for iio_trigger_poll()). - Ensure complete reinitialized before reuse. Previously it would have completed immediate after the first time. ti,ads7950 - Fix return value of gpio_get() to be 0 or 1. - Avoid accidental overwrite of state resulting in gpio_get() only returning 0 or -ERRNO but never 1. * tag 'iio-fixes-for-7.0b' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (25 commits) iio: imu: adis16550: fix swapped gyro/accel filter functions iio: adc: aspeed: clear reference voltage bits before configuring vref iio: adc: ti-ads1119: Reinit completion before wait_for_completion_timeout() iio: adc: ti-ads1018: fix type overflow for data rate iio: adc: ti-ads7950: do not clobber gpio state in ti_ads7950_get() iio: adc: ti-ads7950: normalize return value of gpio_get iio: orientation: hid-sensor-rotation: fix quaternion alignment iio: add IIO_DECLARE_QUATERNION() macro iio: adc: ti-ads1119: Replace IRQF_ONESHOT with IRQF_NO_THREAD iio: imu: bno055: fix BNO055_SCAN_CH_COUNT off by one iio: hid-sensors: Use software trigger iio: adc: ad4062: Replace IRQF_ONESHOT with IRQF_NO_THREAD iio: gyro: mpu3050: Fix out-of-sequence free_irq() iio: gyro: mpu3050: Move iio_device_register() to correct location iio: gyro: mpu3050: Fix irq resource leak iio: gyro: mpu3050: Fix incorrect free_irq() variable iio: imu: st_lsm6dsx: Set buffer sampling frequency for accelerometer only iio: imu: st_lsm6dsx: Set FIFO ODR for accelerometer and gyroscope only iio: dac: mcp47feb02: Fix mutex used before initialization iio: adc: ade9000: fix wrong return type in streaming push ...
