[PATCH] ASoC: Intel: cht_bsw_rt5672: Simplify probe() with local 'dev' pointer

[Sachin Mokashi]

In snd_cht_mc_probe(), &pdev->dev is dereferenced repeatedly throughout
the function. Introduce a local dev pointer
early in the function and use it consistently in place of all open-coded
&pdev->dev references.

It reduces repetition, improves readability, and aligns with the common
kernel driver pattern of caching the device pointer at function entry.

One nit below but it's not a strong for v2.  For the patch:

Weird location for this declaration. Why in the middle of nowhere?

Applied to

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-7.2

Thanks!

[1/1] ASoC: Intel: cht_bsw_rt5672: Simplify probe() with local 'dev' pointer
      https://git.kernel.org/broonie/sound/c/cda1cf0526f1

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

Agreed, will take care of it from the next time.
