Re: [PATCH] The sun50i_iommu_of_xlate() function didn't properly handle the case where of_find_device_by_node() returns NULL. This could lead to a NULL pointer dereference when accessing platform_get_drvdata(iommu_pdev) if the device node couldn't be found.

The subject line is too long, use something short which describes WHAT
the patch does. The WHY can be placed into the commit message.

Thanks,
