From 135721446144af005109c25eeacca4fdddcd9a66 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Tue, 15 Jul 2008 21:21:49 +0200 Subject: ide: remove ->mmio flag from ide_hwif_t Since scc_pata host driver no longer uses IDE PCI layer / ide_dma_setup() and all other ->mmio users set also IDE_HFLAG_MMIO host flag we can safely remove ->mmio flag. There should be no functional changes caused by this patch.

Also, unify the exit path of reset_pollfunc() when returning ide_stopped since the need of ->port_ops->reset_poll() to be treated specially has vanished (way back, it seems).
