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 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 (9): dmaengine: stm32-dmamux: simplify getting .driver_data firmware: meson: simplify getting .driver_data gpio: xilinx: simplify getting .driver_data drm/msm: simplify getting .driver_data drm/panfrost: simplify getting .driver_data iio: common: cros_ec_sensors: simplify getting .driver_data net: mdio: mdio-bcm-iproc: simplify getting .driver_data platform: chrome: cros_ec_sensorhub: simplify getting .driver_data remoteproc: omap_remoteproc: simplify getting .driver_data drivers/dma/stm32-dmamux.c | 14 +++++--------- drivers/firmware/meson/meson_sm.c | 3 +-- drivers/gpio/gpio-xilinx.c | 6 ++---- drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c | 13 +++++-------- drivers/gpu/drm/msm/disp/mdp5/mdp5_kms.c | 6 ++---- drivers/gpu/drm/msm/dp/dp_display.c | 6 ++---- drivers/gpu/drm/msm/dsi/dsi_host.c | 6 ++---- drivers/gpu/drm/msm/msm_drv.c | 3 +-- drivers/gpu/drm/panfrost/panfrost_device.c | 6 ++---- .../common/cros_ec_sensors/cros_ec_sensors_core.c | 3 +-- drivers/net/mdio/mdio-bcm-iproc.c | 3 +-- drivers/platform/chrome/cros_ec_sensorhub.c | 6 ++---- drivers/remoteproc/omap_remoteproc.c | 6 ++---- 13 files changed, 28 insertions(+), 53 deletions(-)
