ide: drop 'timeout' and 'expiry' arguments from ide_pc_intr()
* Move idescsi_expiry() to ide-atapi.c.
* Move get_timeout() to <linux/ide.h>.
* Drop 'timeout' and 'expiry' arguments from ide_pc_intr().
While at it:
* idescsi_expiry() -> ide_scsi_expiry()
* get_timeout() -> ide_scsi_get_timeout()
There should be no functional changes caused by this patch.
