From dcaf9aed995c2b2a49fb86bbbcfa2f92c797ab5d Mon Sep 17 00:00:00 2001 From: Vijaya Mohan Guvva Date: Wed, 4 Dec 2013 05:43:58 -0800 Subject: [PATCH] [SCSI] bfa: Chinook quad port 16G FC HBA claim issue Bfa driver crash is observed while pushing the firmware on to chinook quad port card due to uninitialized bfi_image_ct2 access which gets initialized only for CT2 ASIC based cards after request_firmware(). For quard port chinook (CT2 ASIC based), bfi_image_ct2 is not getting initialized as there is no check for chinook PCI device ID before request_firmware and instead bfi_image_cb is initialized as it is the default case for card type check. This patch includes changes to read the right firmware for quad port chinook.
