[64/68] [PATCH] pata_pdc202xx_old: fix UDMA mode for PDC2026x chipsets

From: Greg KH
Date: Fri Sep 24 2010 - 12:37:14 EST


2.6.32-stable review patch. If anyone has any objections, please let us know.

------------------

commit 750e519da7b3f470fe1b5b55c8d8f52d6d6371e4 upstream.

PDC2026x chipsets need the same treatment as PDC20246 one.

This is completely untested but will hopefully fix UDMA issues
that people have been reporting against pata_pdc202xx_old for
the last couple of years.
