From 8d2f9e8eca807479c83c8f765b6859838da618eb Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 19 May 2014 19:25:48 +0800 Subject: [PATCH] clk: ti: dra7: return error code in failure case Add a returned error code in the MAX_APLL_WAIT_TRIES case. Remove the updating of the return variable r to 0 if MAX_APLL_WAIT_TRIES is not yet reached, because r is already 0 at this point.
