Thierry Reding 4b14874409 pwm: sun4i: Remove erroneous else branch ... [ Upstream commit 6eefb79d6f5bc4086bd02c76f1072dd4a8d9d9f6 ] Commit d3817a6470 ("pwm: sun4i: Remove redundant needs_delay") changed the logic of an else branch so that the PWM_EN and PWM_CLK_GATING bits are now cleared if the PWM is to be disabled, whereas previously the condition was always false, and hence the branch never got executed. This code is reported causing backlight issues on boards based on the Allwinner A20 SoC. Fix this by removing the else branch, which restores the behaviour prior to the offending commit. Note that the PWM_EN and PWM_CLK_GATING bits still get cleared later in sun4i_pwm_apply() if the PWM is to be disabled.
