- Fix a possible NULL-ptr dereference in dev_iommu_priv_get() which is too easy to accidentially trigger from IOMMU drivers. In the current case the AMD IOMMU driver triggered it on some machines in the IO-page-fault path, so fix it once and for all. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEr9jSbILcajRFYWYyK/BELZcBGuMFAmAdawcACgkQK/BELZcB GuN6dg//XtkZJUl7Cf5wBAYv8PRIGTrbS6a4JQ4Eunv4x9Q29Cvqgb813DPO15sB xfR7hTGhWJz9LpZVxX9AxmklVRNFUsng6bIaU8drc0y5rDBm2fjmgRo3zX5DQp+K 120ZwbAK0TIFlyL3nQhqrfnGJN3lMqdMQJ4EbzkQOtk8BkeBWPwYsXvI2PCgvjsY U4SGKh2URaJh59W+PApXUCf5owCPGJoCN2pnGJAmYUmsainTe2FZ79xXGSzvFczH ty4YWphoNimvMUcYzdn/ZTUwA68zlRP6/YgpWxpn3tr0624WUK4LusmzBWgNjPB5 NzYaaOoXHIhqyuFbVd5QXeyoNhKX59ICnV8U8zLvwpT2RHMzVX6hu5Kx7zDy45V3 F7IqHQfAz7ZnEZ8o+SzdN3ZquFfE2/zQCmFY3OQZOCl11behL1o6tY6g244R6oiq VYk2t5whm9K7hbDBclzzIUsax6oK8IX7GBwyy8Xw+k4Qnx/qLmG8txfjax7FBWix km/cAJwIv8mhLL496I6XNtHLzcgwvjLQ0HNT3E1MFj/d+uD0rUxAea9XW/QpO6gc 6+tzL7S9PckX7TY3kuEbvz8b4TWcumSma4tZqiky7iFG+Rxzc+BeMDLMzPZhhpTL 5AuqKLFFs/XeHGo4mqpLKPGlK30qp2GJh5VaTq2cPLA82hkFSSk= =Og2E -----END PGP SIGNATURE----- Merge tag 'iommu-fixes-v5.11-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull IOMMU fix from Joerg Roedel: "Fix a possible NULL-ptr dereference in dev_iommu_priv_get() which is too easy to accidentially trigger from IOMMU drivers.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
