can: hi311x: fix a signedness bug in hi3110_cmd()
The hi3110_cmd() is supposed to return zero on success and negative error codes on failure, but it was accidentally declared as a u8 when it needs to be an int type. Fixes: 57e83fb9b746 ("can: hi311x: Add Holt HI-311x CAN driver") Link: https://lore.kernel.org/r/20210729141246.GA1267@kili Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
