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 (9): net: dsa: bcm_sf2: simplify getting .driver_data net: dsa: qca8k: simplify getting .driver_data net: ethernet: cadence: macb_main: simplify getting .driver_data net: ethernet: davicom: dm9000: simplify getting .driver_data net: ethernet: smsc: smc91x: simplify getting .driver_data net: ethernet: ti: cpsw: simplify getting .driver_data net: ethernet: ti: davinci_emac: simplify getting .driver_data net: ethernet: wiznet: w5300: simplify getting .driver_data net: phy: mdio-mux-bcm-iproc: simplify getting .driver_data drivers/net/dsa/bcm_sf2.c | 6 ++---- drivers/net/dsa/qca8k.c | 6 ++---- drivers/net/ethernet/cadence/macb_main.c | 6 ++---- drivers/net/ethernet/davicom/dm9000.c | 6 ++---- drivers/net/ethernet/smsc/smc91x.c | 3 +-- drivers/net/ethernet/ti/cpsw.c | 6 ++---- drivers/net/ethernet/ti/davinci_emac.c | 6 ++---- drivers/net/ethernet/wiznet/w5300.c | 6 ++---- drivers/net/phy/mdio-mux-bcm-iproc.c | 6 ++---- 9 files changed, 17 insertions(+), 34 deletions(-) -- 2.19.0
