ALSA: hda - Fix 3.9 regression of EAPD init on Conexant codecs
The older Conexant codecs have up to two EAPDs and these are supposed to be rather statically turned on. The new generic parser code assumes the dynamic on/off per path usage, thus it resulted in the silent output on some machines. This patch fixes the problem by simply assuming the static EAPD on for such old Conexant codecs as we did until 3.8 kernel. Reported-and-tested-by: Christopher K. <c.krooss@gmail.com> Cc: <stable@vger.kernel.org> [v3.9] Signed-off-by: Takashi Iwai <tiwai@suse.de>
