From b48b3a390629945f5a131b210931416cf243f58d Mon Sep 17 00:00:00 2001 From: Steven Miao Date: Wed, 29 Jan 2014 12:25:39 +0800 Subject: [PATCH] From: Paul Walmsley blackfin: bf60x: clock: return 0 upon error from clk_round_rate() clk_round_rate() should return 0 upon an error, rather than returning a negative error code. This is because clk_round_rate() is being changed to return an unsigned return type rather than a signed type, since some clock sources can generate rates higher than (2^31)-1 Hz.
