[alsa-devel] [PATCH v2 3/6] ASoC: Intel: Atom: move atom driver to common acpi match

Vinod Koul vinod.koul at intel.com
Thu Nov 5 17:04:12 CET 2015


This patch moves the atom driver to use the common acpi match
functions.  Since atom driver has few more information in machine
table, these are appended to table and set to NULL for common
driver
