Subject[PATCH 4.9 127/206] scsi: g_NCR5380: Fix release_region in error handling
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ondrej Zary <linux@rainbow-software.org>

commit 7b93ca43b7e21fbe6fb1a6f4ecce4a2f70f424a0 upstream.

When a SW-configurable card is specified but not found, the driver
releases wrong region, causing the following message in kernel log:
Trying to free nonexistent resource <0000000000000000-000000000000000f>

Fix it by assigning base earlier.
