Subject: scsi: g_NCR5380: Fix release_region in error handling
From: Ondrej Zary <linux@xxxxxxxxxxxxxxxxxxxx>
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.
