Subject: [PATCH AUTOSEL 4.19 089/205] net: lan78xx: Bail out if lan78xx_get_endpoints fails
Date: Fri, 8 Nov 2019 06:35:56 -0500 [thread overview]
Message-ID: <20191108113752.12502-89-sashal@kernel.org> (raw)
In-Reply-To: <20191108113752.12502-1-sashal@kernel.org>
From: Stefan Wahren <stefan.wahren@i2se.com>
[ Upstream commit fa8cd98c06407b5798b927cd7fd14d30f360ed02 ]
We need to bail out if lan78xx_get_endpoints() fails, otherwise the
result is overwritten.
Fixes: 55d7de9de6c3 ("Microchip's LAN7800 family USB 2/3 to 10/100/1000 Ethernet")
