From 844b9468523c8c2c45b90df4efcabcbe4926b5ab Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Mon, 13 Oct 2008 21:39:31 +0200 Subject: ide: drop 'timeout' and 'expiry' arguments from ide_pc_intr() * Move idescsi_expiry() to ide-atapi.c. * Move get_timeout() to . * 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.
