[PATCH stable-6.6.x 0/3] ASoC: SOF: ipc4-control: Support for Switch and Enum controls

[Peter Ujfalusi <peter.ujfalusi@linux.intel.com>]

Hi,

This is a backport of [1] series for 6.6.x stable kernel.
It is fixing a user reported [2] NULL dereference kernel panic after
updating the SOF firmware and topology files.

While Meteor Lake is not supported by 6.6 kernel, users might need to be
able to use it as a jumping point to update the kernel to a version which
is supporting Meteor Lake (6.7+), a kernel panic should be avoided to
not block the transition.
