Subject: ALSA: hda - Move one-time init codes from generic_hdmi_init()
From: Takashi Iwai <tiwai@xxxxxxx>
commit 8b8d654b55648561287bd8baca0f75f964a17038 upstream.
The codes to initialize work struct or create a proc interface should
be called only once and never although it's called many times through
the init callback. Move that stuff into patch_generic_hdmi() so that
it's called only once.
