From ff7a3267368634e368ebaac68d5e3abf129edd1d Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 28 Nov 2008 15:17:06 +0100 Subject: [PATCH] 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.
