[PATCH v3 0/2] iio: light: iqs621-als: use lock guards and prefer early error handling

[Pedro Barletta Gennari]

Use guard(mutex)() for handling mutex lock instead of manually
locking and unlocking the mutex and flip 'if (!ret)' to 'if (ret)'
to handle errors early in drivers/iio/light/iqs621-als.c

Patch 2 dependes on patch 1
