Subject: [PATCH 3/5] staging: gasket: sysfs: remove unnecessary NULL check on device ptr
Date: Fri, 27 Jul 2018 22:21:58 -0700 [thread overview]
Message-ID: <20180728052200.228796-4-toddpoynor@gmail.com> (raw)
In-Reply-To: <20180728052200.228796-1-toddpoynor@gmail.com>
From: Todd Poynor <toddpoynor@google.com>
The device pointer passed into get_mapping() will never be NULL; the
check is unnecessary.
