of_property_read_bool() should only be used on boolean properties and
not used as a presence check. The of_clk_get_parent_name() function
returns NULL if the "clocks" property is not present, so there is no
need to check for presence first.

Signed-off-by: Rob Herring (Arm) <robh@kernel.org>

v2:
 - Just drop the presence check instead of using of_property_present()
 - Split to separate patch

Applied to

Thanks!

[1/1] ASoC: ak4642: Drop "clocks" property presence check
      https://git.kernel.org/broonie/sound/c/15570f6b54b0

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
