Patches 7 through 17 were provided by Andy Shevchenko. The series was compile-tested and ran in QEMU with i2c-stub and no issues were found. Changes include: - replacing usleep_range() with fsleep() for optimization - migrating to iopoll macros for better device polling - removing unused headers and adding new ones - checkpatch.pl fixes - switching driver to use devm_* functions Signed-off-by: Joshua Crofts --- Changes in v2: - PATCH 1: reverted alphabetical header ordering per logical change separation - PATCH 2: added newline between fsleep() and return - PATCH 3: fixed open parenthesis formatting - PATCH 4: fixed whitespace issues, added for USEC_PER_MSEC macro Changes in v3: - PATCH 1 & 2: split alphabetical ordering and header removal into two separate patches - PATCH 4: commit message fix - PATCH 5 & 6: split error handling and polling loop replacement into two separate patches Changes in v4: - PATCH 7-17: am Andy's changes into this series - PATCH 2, 5, 6: fixup Andy's changes to existing patches Changes in v5: - PATCH 6 & 7: reorder patch series, edit commit messages - PATCH 8: add check for negative val from readx_*() call - Various cleanups --- --- Andy Shevchenko (10): iio: magnetometer: ak8975: avoid using temporary variable iio: magnetometer: ak8975: drop duplicate NULL check iio: magnetometer: ak8975: remove duplicate error message iio: magnetometer: ak8975: reduce usage of magic lengths of the buffer iio: magnetometer: ak8975: unify return code variable name iio: magnetometer: ak8975: switch to using managed resources iio: magnetometer: ak8975: consistently use 'data' parameter iio: magnetometer: ak8975: unify messages with help of dev_err_probe() iio: magnetometer: ak8975: use temporary variable for struct device iio: magnetometer: ak8975: make use of the macros from bits.h Joshua Crofts (8): iio: magnetometer: ak8975: sort headers alphabetically iio: magnetometer: ak8975: update headers per IWYU principle iio: magnetometer: ak8975: replace usleep_range() with fsleep() iio: magnetometer: ak8975: change 'u8*' to 'u8 *' in cast iio: magnetometer: ak8975: fix wrong errno on return iio: magnetometer: ak8975: pass conversion timeouts as arguments iio: magnetometer: ak8975: modernize polling loops with iopoll() macros iio: magnetometer: ak8975: check if gpiod read was successful drivers/iio/magnetometer/ak8975.c | 369 +++++++++++++++++++------------------- 1 file changed, 180 insertions(+), 189 deletions(-) --- base-commit: 440c14da1af1cc6cc9bb18841603711d845ed900 change-id: 20260505-magnetometer-fixes-d3a96180ab4c Best regards, -- Joshua Crofts
