[PATCH v2] ASoC: sun50i-dmic: avoid unused variable warning for sun50i_dmic_of_match
In configurations with CONFIG_OF=n, we get a harmless build warning:
sound/soc/sunxi/sun50i-dmic.c:268:34: warning: unused variable 'sun50i_dmic_of_match' [-Wunused-const-variable]

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.

But I think there is no difference between the two modifications. I refer to other driver files of sunxi (sound/soc/sunxi), all of which are in the same format.
