pwm: imx-tpm: Don't check the return code of pwmchip_remove()

Uwe Kleine-König · thierryreding · commit bfecbc9490dc · 2021-09-02T21:38:52.000+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 pwm_imx_tpm_remove().
