Subject: [PATCH] net: cxgb3_main: Fix a resource leak in a error path in 'init_one()'
Date: Tue,  6 Aug 2019 10:55:12 +0200	[thread overview]
Message-ID: <20190806085512.11729-1-christophe.jaillet@wanadoo.fr> (raw)

A call to 'kfree_skb()' is missing in the error handling path of
'init_one()'.
This is already present in 'remove_one()' but is missing here.
