From: Phil Sutter Date: Tue, 27 Jan 2009 13:35:52 +0000 (+0100) Subject: pata-rb532-cf: use ata_sff_data_xfer32() X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=180bd147f18316d92bd5f59aebc9932cabc03edd;p=openwrt%2Fstaging%2Fblogic.git pata-rb532-cf: use ata_sff_data_xfer32() The biggest difference between rb532_pata_data_xfer() and ata_sff_data_xfer32() is the call to ata_sff_pause() at the end of rb532_pata_data_xfer() which I suppose to be unnecessary since it works without. I've also tested using ata_sff_data_xfer() as replacement, but since we know that the driver supports 32bit IO, using the optimised version should be safe.
