Subject: [PATCH 5.4 35/40] can: hi311x: fix a signedness bug in hi3110_cmd()
Date: Mon,  2 Aug 2021 15:45:15 +0200	[thread overview]
Message-ID: <20210802134336.512272318@linuxfoundation.org> (raw)
In-Reply-To: <20210802134335.408294521@linuxfoundation.org>

From: Dan Carpenter <dan.carpenter@oracle.com>

[ 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.

Fixes: 57e83fb9b746 ("can: hi311x: Add Holt HI-311x CAN driver")
