From add645261560545c947c8778ad51b1eb1f68d51c Mon Sep 17 00:00:00 2001 From: Peter Senna Tschudin Date: Tue, 20 May 2014 12:33:44 +0200 Subject: [PATCH] staging: ft1000: 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.
