[PATCH] ASoC: meson: meson-card-utils: use of_property_present() for DT parsing

[Martin Blumenstingl]

Commit c141ecc3cecd ("of: Warn when of_property_read_bool() is used on
non-boolean properties") added a warning when trying to parse a property
with a value (boolean properties are defined as: absent = false, present
without any value = true). This causes a warning from meson-card-utils.

meson-card-utils needs to know about the existence of the
"audio-routing" and/or "audio-widgets" properties in order to properly
parse them. Switch to of_property_present() in order to silence the
following warning messages during boot:
  OF: /sound: Read of boolean property 'audio-routing' with a value.
  OF: /sound: Read of boolean property 'audio-widgets' with a value.

[1/1] ASoC: meson: meson-card-utils: use of_property_present() for DT parsing
      commit: 171eb6f71e9e3ba6a7410a1d93f3ac213f39dae2

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
