These two patches fix regressions in the Qualcomm APR driver that
prevent audio from working on MSM8916 (and likely MSM8996). In previous
kernel releases the "qcom,protection-domain" property was optional, in
6.2-rc1 it is now required. It should remain optional because the
protection domain functionality is only supported starting with MSM8998
and is not present on older SoCs [1].
These patches should go as fixes into 6.2 to fix the regression.

The protection domain functionality exists only in SoCs starting from
MSM8998 [1], while the APR bindings are also used on older platforms.
Commit 41288c305836 ("ASoC: dt-bindings: qcom,apr: Split services to
shared schema") made the "qcom,protection-domain" required but it
should remain optional to avoid dtbs_check warnings on older platforms,
e.g.:

APR should not fail if the service device tree node does not have
the qcom,protection-domain property, since this functionality does
not exist on older platforms such as MSM8916 and MSM8996.
Ignore -EINVAL (returned when the property does not exist) to fix
a regression on 6.2-rc1 that prevents audio from working:

Forgot that when I reviewed 6d7860f5750d, but you're right. Sorry about
that.
