Hi Michal, Thanks for the reviews! > There are two more occurences in this gpio-zynq driver. > zynq_gpio_resume, zynq_gpio_suspend. It wasn't detected because these > two lines are not together. But the same change can be applied for them too. Not really. The rule would have matched if there was just "something" inbetween. It did not match because the "something" involves the variable 'pdev', so we can't remove it. And just changing towards 'dev_get_drvdata' and keeping 'pdev' was not worth the hazzle in my book. Especially since I think the code should probably get refactored. Calling platform_get_irq() in suspend/resume paths in order to get the irq_data looks a little expensive to me, but I haven't tested it. Best wishes, Wolfram PS: Please quote only relevant parts of the message, it is a lot easier to find comments then IMO.

I just bounced it again. Otherwise, it is here, too, downloadable as

I had the same problem, turned out this got classified as spam by Google for some reason. Maybe try your spam folder? Thierry

Then I'd miss all the new drivers which may need this fixed. Coccinelle makes respinning a breeze, so no problem with that.

Coccinelle > makes respinning a breeze, so no problem with that. Because coccinelle didn't find anything in drivers/gpio, I wondered what case you are referring to? Invoking this (as of v5.1-rc1) gives: $ git log --oneline --grep "simplify getting" drivers/gpio 7ddb7dce0ab6 gpio: gpio-tegra: simplify getting .driver_data 38ccad0243f9 gpio: gpio-zynq: simplify getting .driver_data a3f4f728d3bb gpio: gpio-omap: simplify getting .driver_data 11868645c5b5 gpio: gpio-mxc: simplify getting .driver_data ea5ec5e3aeab gpio: gpio-lynxpoint: simplify getting .driver_data deb19ac533ac gpio: gpio-dwapb: simplify getting .driver_data

We should get drvdata from struct device directly. Going via platform_device is an unneeded step back and forth.
