This patch adds driver data for adl_mx98360a_cs4242 which supports two max98360a speaker amplifiers on SSP1 and cs42l42 headphone codec on SSP0 running on ADL platform. Also add the capability to machine driver of creating DAI Link for BT offload. Although BT offload always uses SSP2 port but we reserve the flexibility to assign the port number in macro.
Title's length seems off. Please shorten it a bit. Commit message formatting (line width) is not cohevise across the lines either.
Another suggestion: skip redundant bits at the front e.g.: s/This patch adds/Add/. When adding new code (new functionality), it's good to plainly state: "To be able to do X we add capability Y". The last sentence in your message is a side note. It's good that you're being transparent here, my only advice is that you add a new line before such notes as these are not the main dish here, really.
Title suggest you're doing two things here - adding support for some ADL configuration (1) and BT audio offload (2). Recommendation is to splitting non-atomic changes so each patch in the series answers single problem.

Isn't there some SND_SOC_DAILINK_DEF() macro for that already?

Looks like there is no need for 'ret' variable here.

This 'goto' statement seems redundant. I might be missing something but returning -ENOMEM should suffice. Label 'devm_err' does not do anything special anyway.

Are the parenthesis needed? Should be save to drop them.

Once 'ret/devm_err' situation is clarified, this block can be dropped.
