ALSA: hda - Don't export symbols when built-in kernel
The global functions in hda_codec.c and other core parts are only for HD-audio codec and controller drivers. When the HD-audio driver is built in kernel, all stuff have to be statically linked, thus we don't need any exports. This patch introduces a conditional macro to do export only when needed. Signed-off-by: Takashi Iwai <tiwai@suse.de>
