From 9977126c4b65c1396b665f7a0eeb8c7dede336f9 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 16 Jul 2007 14:29:38 +0900 Subject: libata: add @is_cmd to ata_tf_to_fis() Add @is_cmd to ata_tf_to_fis(). This controls bit 7 of the second byte which tells the device whether this H2D FIS is for a command or not. This cleans up ahci a bit and will be used by PMP.
