v1->v2: add two prerequisite patches.
This series backports a fix for a NULL pointer dereference in
hda_dai_get_ops() to the 6.6.y stable branch.
The fix (patch 3/3) adds a NULL check for the widget before
dereferencing it. However, it depends on two prerequisite patches that
modify the code context in hda_select_dai_widget_ops():
Patch 1/3: daa09d0615ce ("ASoC: SOF: Intel: hda-dai: remove dspless special case")
Patch 2/3: 2065610b5ddd ("ASoC: SOF: Intel: hda-dai: add support for dspless mode beyond HDAudio")
Patch 3/3: 16c589567a95 ("ASoC: SOF: Intel: hda: Fix NULL pointer dereference")
All three patches apply cleanly to v6.6.140 without adjusting the context.
