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 <[email protected]> Cc: Rafael J.
