stable inclusion from linux-4.19.201 commit 5a6c550c2f0e49492a906ebd08d8af9b455c4fa9
--------------------------------
[ Upstream commit f6b3c7848e66e9046c8a79a5b88fd03461cc252b ]
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.
