pwm: imx: Signedness bug in imx_pwm_get_state()
"ret" only holds zero and negative error codes. It needs to be signed for the error handling to work. Fixes: 9f4c8f9607c3 ("pwm: imx: Add ipg clock operation") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Reviewed-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
