Subject: [PATCH 21/26] staging: vt6656: Don't needlessly test for NULL before release_firmware()
Date: Mon, 9 Apr 2012 22:51:58 +0200 (CEST)	[thread overview]
Message-ID: <alpine.LNX.2.00.1204092239320.14420@swampdragon.chaosbits.net> (raw)
In-Reply-To: <alpine.LNX.2.00.1204092157340.13925@swampdragon.chaosbits.net>

Checking for a NULL pointer before calling release_firmware() is
redundant since the function does that check itself.
