From 1289e9e8b42f973f2ab39e5f4f2239ff826c27e9 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 27 Nov 2008 15:47:11 +0100 Subject: ALSA: hda - Modularize HD-audio driver Split the monolithc HD-audio driver into several pieces: - snd-hda-intel HD-audio PCI controller driver; loaded via udev - snd-hda-codec HD-audio codec bus driver - snd-hda-codec-* Specific HD-audio codec drivers When built as modules, snd-hda-codec (that is invoked by snd-hda-intel) looks up the codec vendor ID and loads the corresponding codec module automatically via request_module(). When built in a kernel, each codec drivers are statically hooked up before probing the PCI. This patch adds appropriate EXPORT_SYMBOL_GPL()'s and the module information for each driver, and driver-linking codes between codec-bus and codec drivers.
