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 Wolfram Sang (6): gpio: gpio-dwapb: simplify getting .driver_data gpio: gpio-lynxpoint: simplify getting .driver_data gpio: gpio-mxc: simplify getting .driver_data gpio: gpio-omap: simplify getting .driver_data gpio: gpio-tegra: simplify getting .driver_data gpio: gpio-zynq: simplify getting .driver_data drivers/gpio/gpio-dwapb.c | 6 ++---- drivers/gpio/gpio-lynxpoint.c | 3 +-- drivers/gpio/gpio-mxc.c | 6 ++---- drivers/gpio/gpio-omap.c | 12 ++++-------- drivers/gpio/gpio-tegra.c | 6 ++---- drivers/gpio/gpio-zynq.c | 6 ++---- 6 files changed, 13 insertions(+), 26 deletions(-) -- 2.19.0
