The logic to check return value of clk_enable() and clk_prepare() is reversed, fix it. Signed-off-by: Axel Lin <axel.lin@xxxxxxxxxx> Cc: <stable@xxxxxxxxxxxxxxx> --- This is v3 of "pwm: spear: Fix enable pwm output". I change the subject line because it also fixes checking return value of clk_prepare(). Also add cc stable.
