Subject: [PATCH v3 01/14] iio: adc: max1027: Fix style
Date: Wed, 15 Sep 2021 17:51:04 +0200 [thread overview]
Message-ID: <20210915155117.475962-2-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20210915155117.475962-1-miquel.raynal@bootlin.com>
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
Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
