From 189c9b8d925691cc58823ffdc3bf75dc8630ccdf Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Mon, 25 Nov 2013 18:04:34 -0800 Subject: [PATCH] cpufreq: SPEAr: clk_round_rate() can return a zero upon error Treat both negative and zero return values from clk_round_rate() as errors. This is needed since subsequent patches will convert clk_round_rate()'s return value to be an unsigned type, rather than a signed type, since some clock sources can generate rates higher than (2^31)-1 Hz. Eventually, when calling clk_round_rate(), only a return value of zero will be considered a error. All other values will be considered valid rates. The comparison against values less than 0 is kept to preserve the correct behavior in the meantime. Signed-off-by: Paul Walmsley Acked-by: Viresh Kumar Signed-off-by: Rafael J.
