In configurations with CONFIG_OF=n, we get a harmless build warning:

Thanks!
[1/1] ASoC: sun50i-dmic: avoid unused variable warning for sun50i_dmic_of_match
commit: 2cfcc1085d3b7b7c893be41034853d4c63a41092
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark

I don't think this is the right direction (remove the of_match_ptr) to
fix the issue.
of_match_ptr(of_table) returns of_table if CONFIG_OF=y, and returns NULL
if CONFIG_OF=n.
So guard the definition of sun50i_dmic_of_match with `#ifdef CONFIG_OF`
should be better.
Many other drivers do it this way.
