From 337bb336b95bd7884fa3a194eafbdf52a0216b2e Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Mon, 9 Dec 2013 18:49:13 -0800 Subject: [PATCH] ALSA: atmel_abdac: 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.
