Subject: [PATCH] can: hi311x: fix a signedness bug in hi3110_cmd()
Git-commit: f6b3c7848e66e9046c8a79a5b88fd03461cc252b
Patch-mainline: v5.14-rc4
References: git-fixes
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")
