Takashi Iwai c2432466f5 ALSA: hda: Fix too short HDMI/DP chmap reporting ... We got a regression report about the HD-audio HDMI chmap, where some surround channels are reported as UNKNOWN. The git bisection pointed the culprit at the commit 9b3dc8aa3f ("ALSA: hda - Register chmap obj as priv data instead of codec"). The story behind scene is like this: - While moving the code out of the legacy HDA to the HDA common place, the patch modifies the code to obtain the chmap array indirectly in a byte array, and it expands it to kctl value array. - At the latter operation, the size of the array is wrongly passed by sizeof() to the pointer. - It can be 4 on 32bit arch, thus too short for 6+ channels. (And that's the reason why it didn't hit other persons; it's 8 on 64bit arch, thus it's usually enough.) The code was further changed meanwhile, but the problem persisted. Let's fix it by correctly evaluating the array size.
