| |
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.
