commit 05909d5c679cf7c9a8a5bc663677c066a546894f upstream. VT1802 codec seems to reset EAPD of other pins in the hardware level, and this was another reason of the silent headphone output on some machines. As a workaround, introduce a new flag indicating to keep the EPAD on to the generic parser, and set it in patch_via.c.
