From: Christophe JAILLET <redacted> [ Upstream commit debea2cd3193ac868289e8893c3a719c265b0612 ] 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. Signed-off-by: Christophe JAILLET <redacted> Signed-off-by: David S.
