putting an error pointer into strerror can be a bit confusing since strerror takes a positive error code but PTR_ERR returns a negative number, so we have to do strerror(-PTR_ERR(errp)). Some places got this wrong already, so introduce a strerrorp function which directly takes an error pointer. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
