Public bug reported: [Impact] On HP platform with a new device TI AMP TAS2781, the patches from [1] aren't enough for enabling the device.
[Fix] Besides the patches (both Linux oem-6.11 and linux-firmware) from [1], we need to cherry-pick two more patches from Linux mainline: 325735e83d7 ALSA: hda/tas2781: Fix index issue in tas2781 hda SPI driver 2afd96a4a0b ALSA: hda/tas2781: Update tas2781 hda SPI driver [Test Plan] 1. Boot up Ubuntu OEM kernel 2. Test if sound works fine [Where problems could occur] This backport is for the hardware enablement of the new device, so it has nothing to do with regression.
