From c9e4bdb7557ad152f8a41301e646403d9f0ad92c Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 6 Dec 2013 09:30:14 +0100 Subject: [PATCH] ALSA: hda - Allow capture-only configuration We have blindly assumed that all valid configurations should have either analog or digital playback, but there can be capture-only configurations. The parser shouldn't escape in such a case.
