[PATCH 07/20] ALSA: Drop device registration from lm4857 driver

Jonas Bonn jonas.bonn at gmail.com
Wed Oct 1 21:47:19 CEST 2008


Device registration should be handled at the machine level and not
in the driver code itself.  This patch removes the device registration
from the driver code in preparation for moving it to the machine
definition.
