Subject: [PATCH 52/55] mlxsw: core: Fix an error handling path in 'mlxsw_core_bus_device_register()'

From: Christophe JAILLET <[email-masked]>
Date: Thu, 10 May 2018 13:26:16 +0200

[ Upstream commit 8ccc113172e4c1ebef45c2433f3c32ed6ae1b9c9 ]

Resources are not freed in the reverse order of the allocation.
Labels are also mixed-up.

Fix it and reorder code and labels in the error handling path of
'mlxsw_core_bus_device_register()'

Fixes: ef3116e5403e ("mlxsw: spectrum: Register KVD resources with devlink")
