From 9b7564a64999597844513604df4a206fa4da3b69 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 25 Mar 2014 10:02:01 +0100 Subject: [PATCH] ALSA: hda - Inform the unexpectedly ignored pins by auto-parser The auto-parser may ignore some pins that could be valid when they don't match with the assumption or if there are way too many pins assigned to the same output type. So far, such a pin has been silently ignored, but it's better to leave a message, which would help for debugging and understanding the problem.
