Subject: [PATCH 3.12 055/142] scsi: lpfc: Add shutdown method for kexec

From: Anton Blanchard <anton@...ba.org>

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

===============

commit 85e8a23936ab3442de0c42da97d53b29f004ece1 upstream.

We see lpfc devices regularly fail during kexec. Fix this by adding a
shutdown method which mirrors the remove method.
