From mboxrd@z Thu Jan 1 00:00:00 1970 From: wsa+renesas@sang-engineering.com (Wolfram Sang) Date: Sun, 21 Oct 2018 22:00:26 +0200 Subject: [PATCH 0/5] pinctrl: simplify getting .driver_data Message-ID: <20181021200032.1833-1-wsa+renesas@sang-engineering.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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 (5): pinctrl: intel: pinctrl-baytrail: simplify getting .driver_data pinctrl: intel: pinctrl-cherryview: simplify getting .driver_data pinctrl: intel: pinctrl-intel: simplify getting .driver_data pinctrl: pinctrl-amd: simplify getting .driver_data pinctrl: pinctrl-at91-pio4: simplify getting .driver_data drivers/pinctrl/intel/pinctrl-baytrail.c | 6 ++---- drivers/pinctrl/intel/pinctrl-cherryview.c | 6 ++---- drivers/pinctrl/intel/pinctrl-intel.c | 6 ++---- drivers/pinctrl/pinctrl-amd.c | 6 ++---- drivers/pinctrl/pinctrl-at91-pio4.c | 6 ++---- 5 files changed, 10 insertions(+), 20 deletions(-) -- 2.19.0
