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

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

[Wolfram Sang]

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

[PATCH 31/61] net: dsa: simplify getting .drvdata

[Wolfram Sang]

We should get drvdata from struct device directly. Going via
platform_device is an unneeded step back and forth.
