-Subject: ALSA: hda - Allow fixed codec-probe mask
-Patch-mainline: 2.6.30-rc1
-References: bnc#502733
-
-Some devices have broken BIOS and they don't set the codec probe-bit
-properly after cleared by the driver. This makes the driver skipping
-the necessary codec slots.
-
-Since BIOS update isn't always easy, now the semantics of probe_mask
-option is changed a bit. When it contains the bit 8 (0x100), the
-lower bits are used to probe that slots regardless of codec-probe bits
-returned by the hardware.
-
-For example, probe_mask=0x103 will force to probe the codec slot #0
-and #1.
