Subject: [SCSI] mptfusion: release resources in error return path
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=653c42d552d0fd0b05485442aed45dd2d62269c0;p=linux-beck.git

[SCSI] mptfusion: release resources in error return path

We should release the resources in error return code path.
The requested pci bars should be released under an error condition,
when mpt_mapresources fails.
