From: Colin Ian King Date: Thu, 24 Feb 2022 22:05:57 +0000 (+0000) Subject: net: dsa: qca8k: return with -EINVAL on invalid port X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=38455fbcc8ece5d4bdc0e6f380abd88db0b208e6;p=linux.git net: dsa: qca8k: return with -EINVAL on invalid port Currently an invalid port throws a WARN_ON warning however invalid uninitialized values in reg and cpu_port_index are being used later on. Fix this by returning -EINVAL for an invalid port value.
