Subject: [PATCH 23/82] ASoC: Intel: Atom: move atom driver to common acpi match
Git-commit: 12cc291b0b58503b3b0e629ac605218df1851ce1
Patch-mainline: 4.5-rc1
References: bsc#1010690

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
