From: Bartlomiej Zolnierkiewicz <bzolnier@xxxxxxxxx> Subject: [PATCH] ide-acpi: cleanup do_drive_set_taskfiles() * ide_noacpi is already checked by ide_acpi_exec_tfs() which is the only user of do_drive_set_taskfiles(). * ide_acpi_exec_tfs() prints sufficient debug info about the device so no need to do it again. * do_drive_get_GTF() + ide_acpi_exec_tfs() make sure that this function will never be called with incorrect gtf_length argument or if device is not present.
