From 34e44fe87437b6a5aad856f15f7a849e5fc137aa Mon Sep 17 00:00:00 2001 From: Rajendra Nayak Date: Mon, 26 Mar 2012 19:01:48 +0530 Subject: [PATCH] clk: Make clk_get_rate() return 0 on error Most users of clk_get_rate() actually assume a non zero return value as a valid rate returned. Returing -EINVAL might confuse such users, so make it instead return zero on error. Besides the return value of clk_get_rate seems to be 'unsigned long'.
