[PATCH v2 1/8] ASoC: simple-card: simplify code

[PATCH v2 2/8] ASoC: simple-card: simplify code

[Jean-Francois Moine]

The DT values are copied to the non-DT structure before being moved to
the card structure.
Set directly the DT values in the card and move the non-DT copy to the
non-DT sequence.

Applied, thanks.  Every patch in this series seems to have the same
subject line - please don't do that, it makes things harder to work
with.

[PATCH v2 3/8] ASoC: simple-card: simplify code

[Jean-Francois Moine]

The OF pointers are put in the stack and then copied to the card
descriptor.
Put them directly at their right place.

[PATCH v2 6/8] ASoC: simple-card: simplify code

[Jean-Francois Moine]

In the non-DT sequence, the platform data is copied as a whole to the
dynamic card info and the same pointer 'cinfo' is used to copy the
platform information to the card.

Use 'priv' as the pointer to the dynamic card info and copy only the
useful information from the platform data.

[PATCH v2 7/8] ASoC: simple-card: simplify code

[Jean-Francois Moine]

The platform data structure contains information which is used only by
the driver, and the driver allocates platform information fields which
are of no use.
Move the driver specific data to a new private structure and cleanup
the platform data structure.

Rename the pointer to the private data structure to 'priv' to avoid confusion with the platform data pointer.
