Subject[PATCH 3.11 064/128] ibmvscsi: Abort init sequence during error recovery
Date
3.11.10.14 -stable review patch.  If anyone has any objections, please let me know.

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

From: Brian King <brking@linux.vnet.ibm.com>

commit 9ee755974bea2f9880e517ec985dc9dede1b3a36 upstream.

If a CRQ reset is triggered for some reason while in the middle
of performing VSCSI adapter initialization, we don't want to
call the done function for the initialization MAD commands as
this will only result in two threads attempting initialization
at the same time, resulting in failures.
