[greybus-dev] [PATCH 00/61] tree-wide: simplify getting .drvdata

I got tired of fixing this in Renesas drivers manually, so I took the big
hammer. Remove this cumbersome code pattern which got copy-pasted too much
already:

- struct platform_device *pdev = to_platform_device(dev);
- struct ep93xx_keypad *keypad = platform_get_drvdata(pdev);
+ struct ep93xx_keypad *keypad = dev_get_drvdata(dev);

I send this out as one patch per directory per subsystem. I think they should
be applied individually. If you prefer a broken out series per subsystem, I can
provide this as well. Just mail me.

A branch (tested by buildbot; only with all commits squashed into one commit
before) can be found here:

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git coccinelle/get_drvdata

Open for other comments, suggestions, too, of course.

Here is the cocci-script I created (after <n> iterations by manually checking
samples):

@@
struct device* d;
identifier pdev;
expression *ptr;
@@
(
- struct platform_device *pdev = to_platform_device(d);
|
- struct platform_device *pdev;
...
- pdev = to_platform_device(d);
)
<... when != pdev
- &pdev->dev
+ d
...>

ptr =
- platform_get_drvdata(pdev)
+ dev_get_drvdata(d)

<... when != pdev
- &pdev->dev
+ d
...>

Kind regards,

Wolfram
