[PATCH v6 0/8] iio: light: opt3001: driver cleanup
Posted by Joshua Crofts 4 days, 20 hours ago
This series deals with cleaning up the TI OPT3001 sensor driver,
moving it to more modern kernel practices and improving the code style.

While reviewing, Jonathan Cameron (and eventually Sashiko) found a race
condition where userspace could start interacting with the device
before the hardware IRQ was set up.

Changes include:
- moving the driver to use devm_* functions
- IWYU cleanups
- removal of unnecessary macros and comments
- using dev_err_probe() in probe and probe path functions
- checkpatch.pl warning cleanups
- fixing a race condition found in opt3001_probe() function
