Date: Sat, 31 May 2014 13:21:59 -0300 From: Peter Senna Tschudin <peter.senna@...il.com> To: Samuel Ortiz <samuel@...tiz.org> Cc: kernel-janitors@...r.kernel.org, netdev@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 4/11 V2] via-ircc: Remove useless return variables This patch remove variables that are initialized with a constant, are never updated, and are only used as parameter of return. Return the constant instead of using a variable. Verified by compilation only.
