Subject: pwm: rcar: Don't check the return code of pwmchip_remove()
X-Git-Tag: v5.15-rc1~23^2~10
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=15d217614fcfde5386f4ebf7c74c6e98df2777c0;p=thirdparty%2Fkernel%2Flinux.git

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

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().
