Subject: ALSA: hda - Allow jack detection when polling is enabled
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=76a19c69d9c971d652e263799536412ec7f8dcf3;p=linux-beck.git

ALSA: hda - Allow jack detection when polling is enabled

Let is_jack_detectable() return true when the jack polling is enabled
for the codec.  VT1708 uses the polling explicitly so we need to allow
it.
