From 4a38e733a75d52e84772fc00d88e32032a235e75 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 11 Mar 2008 11:35:00 +0900 Subject: pata_ali: use atapi_cmd_type() to determine cmd type instead of transfer size pata_ali was using qc->nbytes to determine whether a command is data transfer type or not. As now qc->nbytes can be extended by padding and draining buffers, these tests are not useful anymore. Use atapi_cmd_type() instead. Signed-off-by: Tejun Heo Cc: Alan Cox Cc: Rafael J.
