Subject: [PATCH] qlge: Only free resources if they were allocated
Date: Mon, 25 Jan 2010 10:17:32 -0600 [thread overview]
Message-ID: <1264436252-3740-1-git-send-email-leitao@linux.vnet.ibm.com> (raw)
Currently qlge tries to release regions even if they were not allocated.
This causes messages like the following in the kernel log
Trying to free nonexistent resource <00000000006af400-00000000006af4ff>
Trying to free nonexistent resource <00003c04ff9f4000-00003c04ff9f7fff>
Trying to free nonexistent resource <00003c04ffc00000-00003c04ffcfffff>
This patch fixes the goto logic in order to not release the resources
if they were not allocated.
