[PATCH 0/2] ASoC: tegra: Use of_device_get_match_data

[Aakash Hemadri]

Hi,
	Prefer `of_device_get_match_data` over `of_match_device`. This patch
replaces of_match_device with of_device_get_match_data.

This patch series will apply cleanly on for-next

Prefer `of_device_get_match_data` over `of_match_device`

Retrieve OF match data using `of_device_get_match_data`, this is cleaner
and better expresses intent.

I think this is incorrect.

  const struct of_device_id *of_match_device(...)
  const void *of_device_get_match_data(...)

of_match_device() returns "struct of_device_id *", i.e., "match".

of_device_get_match_data() calls of_match_device() internally, then
returns "match->data".

Thierry, are you sure about your review here?  As others have been
pointing out of_device_get_match_data() returns match->data while
of_match_device() returns the device.

Since I applied the patches please send an incremental fix on top of
what's been applied rather than a v2.

Ugh... good catch. I (naively) assumed this was a mechanical conversion
like one of the many others that have been making the rounds and
evidently wasn't paying enough attention.

Thanks for spotting this, Bjorn!

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.
