Subject: [PATCH 9/9] ide-atapi: remove pc arg to drive->pc_update_buffers
Date: Tue, 16 Dec 2008 08:36:09 +0100	[thread overview]
Message-ID: <1229412969-3552-10-git-send-email-petkovbb@gmail.com> (raw)
In-Reply-To: <1229412969-3552-1-git-send-email-petkovbb@gmail.com>

... however, since this is called with different pc's in ide-tape also, use a
temporary int arg to differentiate between the call sites.

There should be no functionality change resulting from this patch.
