Remove it and migrate the functions over to the new code. Signed-off-by: Matthew Garrett Signed-off-by: Holger Macht  Signed-off-by: Lin Ming Signed-off-by: Jeff Garzik I've also added some prints: pacpi_port_start is called before pacpi_qc_issue but ata_do_set_mode is called after pacpi_qc_issue.. that seems not right, right? Hope this will help someone familiar with that code.. I'll upload full dmesg as well. -- BR Szymon Janc -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.
