In addition to what Frans said, at least for platform drivers you could
avoid adding (mostly) unused platform_device temp vars like these
+ struct platform_device *pdev = to_platform_device(dev);
struct au1xmmc_host *host = platform_get_drvdata(pdev);
by simply doing
- struct au1xmmc_host *host = platform_get_drvdata(pdev);
+ struct au1xmmc_host *host = dev_get_drvdata(dev);
What do you think?
Thanks!
