IIO: ADCs: Sparse friendly claim of direct mode

From: Jonathan Cameron <Jonathan.Cameron@huawei.com> Note that a number of the drivers touched in this series have no obvious active maintainer, so it would be much appreciated if anyone has time to take a look! It is a large series so feel free to review any you have time to look at rather than feeling you need to look at the whole thing! This is effectively part 3 of what will probably be around 5 series focused on moving from iio_device_claim/release_direct_mode() to iio_device_claim/release_direct(). The new form is more consistent with conditional locking semantics and sparse markings have been added that let us detect miss-balance between claim and release. More details can be found in the cover letter of the first series: https://lore.kernel.org/all/20250209180624.701140-1-jic23@kernel.org/ This series focuses on the ADC drivers. Jonathan Cameron (29): iio: adc: vf610: Move claim of direct mode to caller of vf610_read_sample and use guard(mutex) iio: adc: vf610: Switch to sparse friendly iio_device_claim/release_direct() iio: adc: ti-ads1100: Use guard(mutex) to allow direct returns iio: adc: ti-ads1100: Switch to sparse friendly iio_device_claim/release_direct() iio: adc: ti-ads1015: Use guard(mutex) and factor out code for INFO_RAW iio: adc: ti-ads1015: Switch to sparse friendly iio_device_claim/release_direct() iio: adc: stm32-dfsdm: Factor out core of reading INFO_RAW iio: adc: stm32-dfsdm: Switch to sparse friendly iio_device_claim/release_direct() iio: adc: ad4030: Switch to sparse friendly iio_device_claim/release_direct() iio: adc: ad7192: Factor out core of ad7192_write_raw() to simplify error handling. iio: adc: ad7192: Switch to sparse friendly iio_device_claim/release_direct() iio: adc: ad7768-1: Move setting of val a bit later to avoid unnecessary return value check iio: adc: ad7768-1: Switch to sparse friendly iio_device_claim/release_direct() iio: adc: ad7606: Switch to sparse friendly iio_device_claim/release_direct() iio: adc: ad7791: Factor out core of ad7791_write_raw() to simplify error handling iio: adc: ad7791: Switch to sparse friendly iio_device_claim/release_direct() iio: adc: ad7793: Factor out core of ad7793_write_raw() to simplify error handling iio: adc: ad7793: Switch to sparse friendly iio_device_claim/release_direct() iio: adc: ad799x: Switch to sparse friendly iio_device_claim/release_direct() iio: adc: ad_sigma_delta: Switch to sparse friendly iio_device_claim/release_direct() iio: adc: at91-sama5d2: Move claim of direct mode up a level and use guard() iio: adc: at91-sama5d2: Switch to sparse friendly iio_device_claim/release_direct() iio: adc: max1027: Move claim of direct mode up one level and use guard() iio: adc: max1027: Switch to sparse friendly iio_device_claim/release_direct() iio: adc: max11410: Factor out writing of sampling frequency to simplify errro paths. iio: adc: max11410: Switch to sparse friendly iio_device_claim/release_direct() iio: adc: mxs-lradc: Switch to sparse friendly iio_device_claim/release_direct() iio: adc: rcar: Switch to sparse friendly iio_device_claim/release_direct() iio: adc: Switch to sparse friendly iio_device_claim/release_direct() drivers/iio/adc/ad4030.c | 21 ++-- drivers/iio/adc/ad7173.c | 9 +- drivers/iio/adc/ad7192.c | 119 ++++++++++---------- drivers/iio/adc/ad7266.c | 7 +- drivers/iio/adc/ad7298.c | 7 +- drivers/iio/adc/ad7380.c | 56 +++++----- drivers/iio/adc/ad7476.c | 7 +- drivers/iio/adc/ad7606.c | 14 ++- drivers/iio/adc/ad7768-1.c | 10 +- drivers/iio/adc/ad7791.c | 31 +++--- drivers/iio/adc/ad7793.c | 80 +++++++------- drivers/iio/adc/ad7887.c | 7 +- drivers/iio/adc/ad7923.c | 7 +- drivers/iio/adc/ad7944.c | 7 +- drivers/iio/adc/ad799x.c | 14 ++- drivers/iio/adc/ad_sigma_delta.c | 7 +- drivers/iio/adc/at91-sama5d2_adc.c | 54 +++++----- drivers/iio/adc/dln2-adc.c | 7 +- drivers/iio/adc/max1027.c | 37 +++---- drivers/iio/adc/max11410.c | 72 ++++++------- drivers/iio/adc/mxs-lradc-adc.c | 14 ++- drivers/iio/adc/rcar-gyroadc.c | 9 +- drivers/iio/adc/stm32-adc.c | 7 +- drivers/iio/adc/stm32-dfsdm-adc.c | 76 +++++++------ drivers/iio/adc/ti-adc084s021.c | 9 +- drivers/iio/adc/ti-adc108s102.c | 7 +- drivers/iio/adc/ti-ads1015.c | 168 ++++++++++++----------------- drivers/iio/adc/ti-ads1100.c | 44 +++----- drivers/iio/adc/ti-ads1298.c | 7 +- drivers/iio/adc/ti-ads131e08.c | 14 ++- drivers/iio/adc/ti-tlc4541.c | 7 +- drivers/iio/adc/vf610_adc.c | 36 +++---- 32 files changed, 440 insertions(+), 531 deletions(-)
