[PATCH] ALSA: hda - Fix unused warnings when !SND_HDA_NEEDS_RESUME

From: Mike Waychison
Date: Wed Apr 20 2011 - 15:04:49 EST


When SND_HDA_NEEDS_RESUME is not defined, the compiler identifies that
the following symbols are static but not used:

restore_shutup_pins
hda_cleanup_all_streams

Fix warnings by adding SND_HDA_NEEDS_RESUME guards.

v2:
- Applies to v2.6.39-rc4.
- Dropped moving ad198x_power_eapd and ad198x_power_eapd_write at
Takashi Iwai <tiwai@xxxxxxx>'s request.
