From c5139bd9a9d78053a4da5047deb34e478a52d669 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Herv=C3=A9=20Poussineau?= Date: Thu, 20 Sep 2012 22:50:17 +0200 Subject: [PATCH] fdc: fix FD_SR0_SEEK for non-DMA transfers and multi sectors transfers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
