I hope you're not going about doing this _broken_ thing and thinking "if there's no platform_get_drvdata(), then there shouldn't be any platform_set_drvdata()" because that is WRONG. Wrong wrong wrong wrong wrong. platform_set_drvdata(pdev, foo); sets the driver data on dev, and is basically implemented as: dev_set_drvdata(&pdev->dev, foo); So, to access the driver data, one can either use: platform_get_drvdata(pdev) or: dev_get_drvdata(dev) where one is dealing with a "struct device" pointer. So, the lack of any platform_get_drvdata() does *NOT* mean that platform_set_drvdata() can be removed. If that's what you've been doing, you are *creating* bugs - and you need to stop until you properly understand what you are doing. Thanks anyway, but... your change is totally wrong and will wreck the driver, causing it to oops the kernel. Strong and definite NAK. I do *NOT* expect to ever see a patch like this again for this driver. Thanks. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up.
