[PATCH] pwm: ab8500: Don't check the return code of pwmchip_remove()

From: zhaoxiao
Date: Wed Sep 08 2021 - 02:03:03 EST


pwmchip_remove() returns always 0. Don't use the value to make it
possible to eventually change the function to return void. Also the
driver core ignores the return value of ab8500_pwm_remove()
and considers the device removed anyhow. So returning early results
in a resource leak.
