From 20cd93be67f967c57e5abf62bf5652a00c66b9f0 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Wed, 23 Jul 2008 19:56:00 +0200 Subject: [PATCH] ide-floppy: pass packet command in rq->cmd Make a redundant copy of the packet command bits into rq->cmd. Later, after all drivers have been converted, it'll be switched to use that in the common code instead of pc->c. There should be no functionality change resulting from this patch.
