Subject: ALSA: emu10k1: Fix dock firmware loading
From: Takashi Iwai <tiwai@xxxxxxx>
commit e08b34e86dfdb72a62196ce0f03d33f48958d8b9 upstream.
The commit [b209c4df: ALSA: emu10k1: cache emu1010 firmware] broke the
firmware loading of the dock, just (mistakenly) ignoring a different
firmware for docks on some models. This patch revives them again.
