5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Benjamin Coddington <bcodding@xxxxxxxxxx>
[ Upstream commit 1530827b90025cdf80c9b0d07a166d045a0a7b81 ]
The error path for blocklayout's device lookup is missing a reference drop
for the case where a lookup finds the device, but the device is marked with
NFS_DEVICEID_UNAVAILABLE.
Fixes: b3dce6a2f060 ("pnfs/blocklayout: handle transient devices")
