This series builds on top of Stepan Ionichev's devm error path fix [1] and: - Replaces SET_RUNTIME_PM_OPS() with DEFINE_RUNTIME_DEV_PM_OPS(). - Sorts the driver headers alphabetically. - Returns -ENODATA when match data is missing. - Uses a local device pointer in probe. - Converts suitable error paths to dev_err_probe(). - Drops unneeded '< 0' error checks for functions returning 0 or error. - Converts mutex initialization to devm_mutex_init(). - Transitions runtime PM setup to devm_pm_runtime_set_active_enabled(). - Inlines the redundant ads1015_set_conv_mode() helper. - Replaces custom shift macros with FIELD_PREP()/FIELD_GET(). [1] https://lore.kernel.org/all/20260529183708.17819-1-sozdayvek@gmail.com/ --- v5: - Reordered patches: inlined ads1015_set_conv_mode() before applying FIELD_PREP() to completely eliminate code churn. - Extracted FIELD_PREP() evaluations into local variables for regmap_update_bits() calls to ensure clean line lengths and readability. - Added a patch to return -ENODATA when i2c_get_match_data() fails, as requested by Andy Shevchenko. - Split devm_mutex_init() into its own patch to decouple it from the runtime PM modernization, as requested by Andy Shevchenko. v4: https://lore.kernel.org/linux-iio/20260827172100.39176-1-architanant5@gmail.com/ Archit Anant (10): iio: adc: ti-ads1015: use DEFINE_RUNTIME_DEV_PM_OPS() iio: adc: ti-ads1015: sort headers alphabetically iio: adc: ti-ads1015: return -ENODATA when match data is missing iio: adc: ti-ads1015: use local device pointer in probe iio: adc: ti-ads1015: use dev_err_probe() for error handling iio: adc: ti-ads1015: drop unneeded < 0 error checks iio: adc: ti-ads1015: use devm_mutex_init() iio: adc: ti-ads1015: use managed runtime PM setup iio: adc: ti-ads1015: inline ads1015_set_conv_mode() iio: adc: ti-ads1015: replace custom shift macros with FIELD_PREP/GET drivers/iio/adc/ti-ads1015.c | 160 +++++++++++++++++------------------ 1 file changed, 76 insertions(+), 84 deletions(-) -- 2.39.5
