[PATCH 0/4] ASoC: simple-card: tidyup unreadable code

[Kuninori Morimoto]

Hi Mark

These are not a big deal, but tidyup/cleanup unreadable code
on simple-card/simple-scu-card driver.

Kuninori Morimoto (4):
  1) ASoC: simple-card: use defined dev on probe()
  2) ASoC: simple-scu-card: use defined dev on probe()
  3) ASoC: simple-card: add new simple_priv_to_card() macro
  4) ASoC: simple-scu-card: add new simple_priv_to_card() macro

[PATCH 1/4] ASoC: simple-card: use defined dev on probe()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Current asoc_simple_card_probe() already has dev definition,
but some place doesn't use it. Let's fix this issue.

Applied "ASoC: simple-card: use defined dev on probe()" to the asoc tree

[Mark Brown]

The patch

   ASoC: simple-card: use defined dev on probe()

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

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

Applied "ASoC: simple-scu-card: add new simple_priv_to_card() macro" to the asoc tree

[Mark Brown]

The patch

   ASoC: simple-scu-card: add new simple_priv_to_card() macro

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

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

Subject: [PATCH] ASoC: simple-scu-card: add new simple_priv_to_card() macro

Current simple card driver is directly calling priv->snd_card
everywhere, but it makes unreadable code.
Let's use simple_priv_to_card() macro for it
