Subject: Revert "ALSA: hda - Use position_fix=3 as default for AMD chipsets"
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=314c3ff47643c7c1f11317f81a80902af80795e3;p=mv-sheeva.git

Revert "ALSA: hda - Use position_fix=3 as default for AMD chipsets"

This reverts commit 447ee6a7cbbfb5ae7ab8f9b8b058b4a04fe398bf.

The workaround introduced by this commit seems bogus.
The AMD chipsets don't provide proper position-buffer nor FIFO value
required by VIACOMBO fix.
