Subject: [ 121/262] SCSI: lpfc: fix problems with -Werror

From: Greg KH <gregkh@...uxfoundation.org>

3.5-stable review patch.  If anyone has any objections, please let me know.

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

From: James Bottomley <jbottomley@...allels.com>

commit 4bdd03e61b7a5c4c6bc2b25d46fcd491788fdfb3 upstream.

Commit d38bd3aef ("Add -Werror compilation flag") is causing build breakage
with random gcc incarnations.  These look like gcc problems, but we shouldn't
break the build because of a bad gcc.  Fix this by adding a make flag

WARNINGS_BECOME_ERRORS=1

which is the same as aic7xxx uses so ordinarily the build doesn't use -Werror
