From ef940b0403d4ae133c548b01fe64c74fa8a2f0b1 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 28 Sep 2011 20:12:08 +0200 Subject: ALSA: hda - Allow patching with any vendor/subsystem ids In the ugly real world, there area really broken devices that don't set codec SSID correctly. In such a case, the ID can be random, thus the patching won't work reliably. For applying the patch forcibly to such a device, the driver will skip the vendor and/or subsystem ID checks when zero or a negative number is given in [codec] section.
