From 69253b6108102834c7cac826d4c34a0414b83a3e Mon Sep 17 00:00:00 2001 From: Peter Senna Tschudin Date: Sat, 31 May 2014 13:12:26 -0300 Subject: [PATCH] cw1200: 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. The coccinelle script that find and fixes this issue is: // @@ type T; constant C; identifier ret; @@ - T ret = C; ... when != ret when strict return - ret + C ; // Signed-off-by: Peter Senna Tschudin Signed-off-by: John W.
