We should get drvdata from struct device directly. Going via platform_device is an unneeded step back and forth. Signed-off-by: Wolfram Sang --- Build tested only. buildbot is happy. Please apply individually. drivers/iommu/qcom_iommu.c | 6 ++ 1 file

[PATCH 00/61] tree-wide: simplify getting .drvdata

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); +

[PATCH] iommu/iova: Update cached node pointer when current node fails to get any free IOVA

The performance drop is observed with long hours iperf testing using 40G cards. This is mainly due to long iterations in finding the free iova range in 32bit address space. In current implementation for 64bit PCI devices, there is always first attempt to allocate iova from 32bit(SAC preferred
