Subject: [PATCH] firmware: Drop unused pages field from struct firmware
Date:   Wed, 15 Apr 2020 18:45:00 +0200
Message-Id: <20200415164500.28749-1-tiwai@suse.de>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The struct firmware contains a page table pointer that was used only
internally in the past.  Since the actual page tables are referred
from struct fw_priv and should be never from struct firmware, we can
drop this unused field gracefully.
