Subject: [PATCH 0/9] net: simplify getting .driver_data
Date: Sun, 21 Oct 2018 22:00:11 +0200 [thread overview]
Message-ID: <20181021200021.1693-1-wsa+renesas@sang-engineering.com> (raw)
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);
A branch, tested by buildbot, can be found here:
git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git coccinelle/get_drvdata
I have been asked if it couldn't be done for dev_set_drvdata as well. I checked
it and did not find one occasion where it could be simplified like this. Not
much of a surprise because driver_data is usually set in probe() functions
which access struct platform_device in many other ways.
I am open for other comments, suggestions, too, of course.
Here is the cocci-script I created:
@@
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
