[PATCH] scsi: qla2xxx: fix unused function warning

[PATCH] scsi: qla2xxx: fix unused function warning

[Arnd Bergmann]

In what seems to be a mismatch between the scsi-fixes branch and
the scsi-mkp/for-next branch, a newly introduced variable from
one patch got obsoleted in another one:

drivers/scsi/qla2xxx/qla_os.c: In function '__qla2x00_abort_all_cmds':
drivers/scsi/qla2xxx/qla_os.c:1791:11: error: unused variable 'status' [-Werror=unused-variable]

Remove the variable again.

Fixes: c4e521b654e1 ("scsi: qla2xxx: Split the __qla2x00_abort_all_cmds() function")
Fixes: f2ffd4e5bc7b ("scsi: qla2xxx: Timeouts occur on surprise removal of QLogic adapter")

When I prepared commit c4e521b654e1 I verified that my patch did not produce any
warnings when building with W=1. So something must be wrong at your side. Did you
perhaps start from linux-next to prepare this patch? If so, please submit this
patch to Stephen Rothwell.

Yes, I tried to make clear that the two branches are fine by themselves, sorry
if I was still ambiguous. The patch is currently only needed on linux-next
as far as I can tell, but we should avoid getting the same error when the
branches are merged in mainline.

It should be fixed in linux-next as of the next release.  It was just a
problem with the original merge which I fixed when I did my version of
it.
