pwm: rcar: Don't check the return code of pwmchip_remove()

Uwe Kleine-König · thierryreding · commit 15d217614fcf · 2021-09-02T21:38:53.000+02:00
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 rcar_pwm_remove().
