[alsa-devel] [PATCH] Merge es1688 and es968 drivers

1 May 2010

From: Krzysztof Helt krzysztof.h1@wp.pl
The ESS ES968 chip is nothing more then a PnP companion
for non-PnP audio chips. It was paired with non-PnP ESS' chips:
ES688 and ES1688. The ESS' audio chips are handled by the es1688
driver in native mode. The PnP cards are handled by the ES968
driver in SB compatible mode.
Move the ES968 chip handling to the es1688 driver so the driver
can handle both PnP and non-PnP cards. The es968 is removed.
Also, a new PnP id is added for the card I acquired (the change
was tested on this card).
