ide: remove ide_do_drive_cmd()
* Use elv_add_request() instead of __elv_add_request() in ide_do_drive_cmd(). * ide_do_drive_cmd() is used only in ide-{atapi,cd}.c so inline it there. There should be no functional changes caused by this patch. Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
