Subject[PATCH v2 01/16] iio: adc: max1027: Fix style
Date
Follow checkpatch.pl's main advices before hacking into the driver, mainly:
WARNING: Prefer 'unsigned int' to bare use of 'unsigned'
WARNING: Prefer 'unsigned int *' to bare use of 'unsigned *'
CHECK: Comparison to NULL could be written "!foo"
CHECK: Alignment should match open parenthesis
