Subject: [PATCH 3/3] ser_gigaset: remove unnecessary kfree() calls from release method
Date: Tue, 8 Dec 2015 12:00:33 +0100 (CET) [thread overview]
Message-ID: <61b60d7eff05eddf305460f3dae2b80221f08aad.1449570042.git.tilman@imap.cc> (raw)
In-Reply-To: <cover.1449570042.git.tilman@imap.cc>
device->platform_data and platform_device->resource are never used
and remain NULL through their entire life. Drops the kfree() calls
for them from the device release method.
