Subject: [patch net v2 08/10] mlxsw: spectrum: Add missing rollbacks in error path
Date: Wed, 17 Aug 2016 16:39:35 +0200 [thread overview]
Message-ID: <1471444777-3412-9-git-send-email-jiri@resnulli.us> (raw)
In-Reply-To: <1471444777-3412-1-git-send-email-jiri@resnulli.us>
From: Ido Schimmel <idosch@mellanox.com>
While going over the code I noticed we are missing two rollbacks in the
port's creation error path. Add them and adjust the place of one of them
in the port's removal sequence so that both are symmetric.
Fixes: 56ade8fe3fe1 ("mlxsw: spectrum: Add initial support for Spectrum ASIC")
