Subject[PATCH AUTOSEL 5.3 20/68] nvme: fix an error code in nvme_init_subsystem()
Date
From: Dan Carpenter <dan.carpenter@oracle.com>

[ Upstream commit bc4f6e06a90ea016855fc67212b4d500145f0b8a ]

"ret" should be a negative error code here, but it's either success or
possibly uninitialized.

Fixes: 32fd90c40768 ("nvme: change locking for the per-subsystem controller list")
