From 20952b699035448d2277c64efc5910a31be66ed1 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 31 May 2006 18:27:23 +0900 Subject: [PATCH] [PATCH] libata: set PIO-0 after successful EH reset Set ata_device->pio_mode to XFER_PIO_0 after a successful reset. This is to keep EH resets consistent with probe resets as updated by the commit b6079ca409bf88c248992e96510dd6f610f7ed89. Note that, with soon-to-follow hotplug update, EH resets will include probe resets.
