staging: fsl-mc: add support for device table matching
Move the definition of fsl_mc_device_id to its proper location in mod_devicetable.h, and add fsl-mc bus support to devicetable-offsets.c and file2alias.c to enable device table matching. With this patch udev based module loading of fsl-mc drivers is supported. Signed-off-by: Stuart Yoder <stuart.yoder@nxp.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
