From ed67b92385a5afddc98d5ff0894b2854c4a54dac Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 19 Oct 2007 00:30:10 +0200 Subject: [PATCH] ide: add IDE_HFLAG_ERROR_STOPS_FIFO host flag Add IDE_HFLAG_ERROR_STOPS_FIFO host flag and use it instead of hwif->err_stops_fifo. As a side-effect this change fixes hwif->err_stops_fifo not being restored by ide_hwif_restore().
