From mboxrd@z Thu Jan 1 00:00:00 1970 From: Bartlomiej Zolnierkiewicz Subject: [PATCH 1/3] ide: use ata_id_is_cfa() Date: Sat, 2 Aug 2008 19:08:13 +0200 Message-ID: <200808021908.13984.bzolnier@gmail.com> Mime-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Return-path: Content-Disposition: inline Sender: linux-kernel-owner@vger.kernel.org To: linux-ide@kernel.org Cc: linux-kernel@vger.kernel.org List-Id: linux-ide@vger.kernel.org Use ata_id_is_cfa() in do_identify() instead of open-coding check for CompactFlash devices (the inline helper also takes care of detecting CFs advertising themselves as ATA disks).
