From: Kevin Wolf
Subject: [Qemu-devel] [PATCH 15/26] fdc: fix FD_SR0_SEEK for non-DMA transfers and multi sectors transfers
Date: Wed, 14 Nov 2012 19:47:16 +0100

From: Hervé Poussineau <address@hidden>

On non-DMA transfers, fdctrl_stop_transfer() used to set FD_SR0_SEEK
no matter if there actually was a seek or not. This is obviously wrong.

fdctrl_seek_to_next_sect() has this information because it performs
the seek itself.
