iio: light: veml6070: fix veml6070_read() return value

2026-03-26T08:22:33+00:00

veml6070_read() computes the sensor value in ret but returns 0 instead of the actual result. This causes veml6070_read_raw() to always report 0. Return the computed value instead of 0. Running make W=1 returns no errors. I was unable to test the patch because I do not have the hardware. Found by code inspection.

iio: light: vcnl4035: fix scan buffer on big-endian

2026-03-21T20:59:50+00:00

Rework vcnl4035_trigger_consumer_handler() so that we are not passing what should be a u16 value as an int * to regmap_read(). This won't work on bit endian systems. Instead, add a new unsigned int variable to pass to regmap_read(). Then copy that value into the buffer struct. The buffer array is replaced with a struct since there is only one value being read. This allows us to use the correct u16 data type and has a side-effect of simplifying the alignment specification. Also fix the endianness of the scan format from little-endian to CPU endianness. Since we are using regmap to read the value, it will be CPU-endian.

iio: light: bh1780: fix PM runtime leak on error path

2026-02-23T08:24:37+00:00

Move pm_runtime_put_autosuspend() before the error check to ensure the PM runtime reference count is always decremented after pm_runtime_get_sync(), regardless of whether the read operation succeeds or fails.

iio: core: Match iio_device_claim_*() semantics and implementation

2026-01-22T20:53:17+00:00

Implement iio_device_claim_buffer_mode() fully inline with the use of __iio_dev_mode_lock(), which takes care of sparse annotations. To completely match iio_device_claim_direct() semantics, we need to also change iio_device_claim_buffer_mode() return semantics to usual true/false conditional lock semantics. Additionally, to avoid silently breaking out-of-tree drivers, rename iio_device_claim_buffer_mode() to iio_device_claim_try_buffer_mode().
