Subject: [patch] Input: lm8323 - missing error check in lm8323_set_disable()
Date: Wed, 3 Dec 2014 00:17:10 +0300 [thread overview]
Message-ID: <20141202211710.GA19955@mwanda> (raw)
The missing error handling here is not especially harmful but static
checkers complain that "i" can be used uninitialized.
