Mark Pearson 4dc123500c ALSA: hda: ignore invalid NHLT table ... [ Upstream commit a14a6219996ee6f6e858d83b11affc7907633687 ] On some Lenovo systems if the microphone is disabled in the BIOS only the NHLT table header is created, with no data. This means the endpoints field is not correctly set to zero - leading to an unintialised variable and hence invalid descriptors are parsed leading to page faults. The Lenovo firmware team is addressing this, but adding a check preventing invalid tables being parsed is worthwhile. Tested on a Lenovo T14.
