From 989e0aac1a801e9e9580632c9fd448a7aaca596a Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 30 Dec 2016 15:01:17 +0100 Subject: [PATCH] ata: pass queued command to ->sff_data_xfer method For Atari Falcon PATA support we need to check the current command in its ->sff_data_xfer method. Update core code and all users accordingly. There should be no functional changes caused by this patch.
