[PATCH 0/9] Refactor Vangogh acp5x machine driver

[PATCH 0/9] Refactor Vangogh acp5x machine driver

[Lucas Tanure]

Provide small fixes and refactor the code for easier insertion of a new
platform using the same acp5x machine driver.

Lucas Tanure (9):
  ASoC: amd: vangogh: Remove unnecessary init function
  ASoC: amd: vangogh: Update code indentation
  ASoC: amd: vangogh: use sizeof of variable instead of struct type
  ASoC: amd: vangogh: remove unnecessarily included headers
  ASoC: amd: vangogh: use for_each_rtd_components instead of for
  ASoC: amd: vangogh: Check Bit Clock rate before snd_soc_dai_set_pll
  ASoC: amd: vangogh: Move nau8821 and CPU side code up for future
    platform
  ASoC: amd: vangogh: Centralize strings definition
  ASoC: amd: vangogh: Include cs35l41 in structs names

[PATCH 2/9] ASoC: amd: vangogh: Update code indentation

[Lucas Tanure]

Make use of 100 character limit and modify indentation so code is
easier to read.
While at it:
 - sort includes in alphabetical order
 - sort variables declarations by line length
 - use smaller variables names
 - remove unnecessary "struct snd_soc_card *card" lines
 - insert blank lines before return
 - align defines

[PATCH 3/9] ASoC: amd: vangogh: use sizeof of variable instead of struct type

[Lucas Tanure]

Use sizeof(*machine) instead of sizeof(struct acp5x_platform_info)

There is a possibility of bug when variable type has changed but
corresponding struct passed to the sizeof has not.

I'm having a *really* hard time seeing this as helping with
legibility, it just makes things worse when viewed at 80 columns
but it's hard to see what it helps.  The 100 column limit is
flexibility we can use to avoid contortions but this is fairly
natural.

These changes don't obviously correspond to the description of
the patch.  It looks like there's at least some renaming and
reindentation of things not related to DAI names here.  TBH I'm
not sure the removal of namespacing is a good idea, it's probably
not *super* likely but we might run into collisions.
