Merge tag 'iio-fixes-for-6.15a' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-linus
Jonathan writes: IIO: 1st set of fixes for the 6.15 cycle. A mixed bunch of fixes for new and ancient issues found. multiple driver sets: - Stop leaking wakeup sources on device unbind. - Various timestamp alignment fixes that came up as part of work to add runtime checks on buffer sizing. Similarly a DMA buffer safety fix. hid-sensor-prox - Fix a bad merge conflict resolution that lost some variable assignments. - Fix handling of scale when multiple channels present. - Fix wrong application of exponent in offset calculation. adi,ad7380 - Disable offload before using the SPI bus. - Fix a wrong shift on the event threshold. adi,ad7606 - Check there is a sw_mode_config callback before using it as not all busses define one. - Fix missing hold of chip select on in multi word accesses. adi,ad7861 - Fix wrong logic on storing of mode. adi,adis16201 - Wrong resolution for inclinometer channel. adi,adxl367 - Use fresh ODR when setting activity time, not previous value. bosch,bmi270 - Fix initial sampling frequency configuration which was using the wrong register mask. rockchip,saradc - Fix clock initialization sequence to get frequency after get + enable, not before. st,lsm6dsx - Avoid 2 potential infinite loops if we see empty FIFOs ti,opt3001 - Fix a deadlock that can occur due to concurrent access to a flag. * tag 'iio-fixes-for-6.15a' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (28 commits) iio: adis16201: Correct inclinometer channel resolution iio: adc: ad7606: fix serial register access iio: pressure: mprls0025pa: use aligned_s64 for timestamp iio: imu: adis16550: align buffers for timestamp staging: iio: adc: ad7816: Correct conditional logic for store mode iio: adc: ad7266: Fix potential timestamp alignment issue. iio: adc: ad7768-1: Fix insufficient alignment of timestamp. iio: adc: dln2: Use aligned_s64 for timestamp iio: accel: adxl355: Make timestamp 64-bit aligned using aligned_s64 iio: temp: maxim-thermocouple: Fix potential lack of DMA safe buffer. iio: chemical: pms7003: use aligned_s64 for timestamp iio: chemical: sps30: use aligned_s64 for timestamp iio: imu: inv_mpu6050: align buffer for timestamp iio: imu: st_lsm6dsx: Fix wakeup source leaks on device unbind iio: adc: qcom-spmi-iadc: Fix wakeup source leaks on device unbind iio: accel: fxls8962af: Fix wakeup source leaks on device unbind iio: adc: ad7380: fix event threshold shift iio: hid-sensor-prox: Fix incorrect OFFSET calculation iio: hid-sensor-prox: support multi-channel SCALE calculation iio: hid-sensor-prox: Restore lost scale assignments ...
