I assume the change is fine. However I don't understand the commit log.
My guess is you mean:

	mtk_disp_pwm_get_state() wrongly uses bit 0 of CON0 to judge if the
	PWM is enabled. However that is indicated by a bit (at a machine
	dependent position) in the DISP_PWM_EN register. Fix this
	accordingly.

Nitpick: There is no empty line between Fixes: and S-o-b.
