Subject: [patch] Input: pxa27x_keypad - remove an unneeded NULL check
Date: Wed, 11 Feb 2015 13:28:02 +0300 [thread overview]
Message-ID: <20150211102802.GD18515@mwanda> (raw)
Static checkers complain about this NULL check because we dereference it
without checking a couple lines later. This function is only called
when "keypad->pdata" is non-NULL so we can just delete the NULL test.
