Another fix, this time in common IOMMU sysfs code - In the conversion from the old iommu sysfs-code to the iommu_device_register interface, I missed to update the release path for the struct device associated with an IOMMU. It freed the 'struct device', which was a pointer before, but is now embedded in another struct. Freeing from the middle of allocated memory had all kinds of nasty side effects when an IOMMU was unplugged. Unfortunatly nobody unplugged and IOMMU until now, so this was not discovered earlier. The fix is to make the 'struct device' a pointer again. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABAgAGBQJZor4gAAoJECvwRC2XARrj3CUP/3/rhNhHfuvq0C+Nz+ikzZSg xavSSbZztC3SQnr9bgky5TP8Djf9zXzD6DiEGhJoOr98K7R/nvFyaR1NfYnIwHi3 ofngfOcEuuNzInO9L0huHlkqlbUxEwcWTi/QbrFm+W2iL6vOgYejlspFLXAPviDo BlSzJTHzeyXJPZqKDuKB2oO+fVk/xor7KEelsh5fsRrBwFl/JclH5SwIusv4ORfJ sY+02Z8MfLx5+NUvSDj/APoGOlYn0T+XipvduIp2wDtQBmDvN332KWqB1JnAKVdM j27l0BnHABbe5TjQMzj3opAl2v2ZsUqRzolfJdvrh8Gr3gLT1LyMn8A3CRzelBDI jzNsPp9BG2z8enUrppy6yZwv95uxEvNrwrc7jmX46UK12Gf7eBlNGLSe4u+5Ctj5 5e6Eui5y5g/4/DW+BbXt+DjYZHwqJdC1+KAI9XR6sMPRweEmdLhclqgtYhTjGGX9 w2swhpWjcZ7bte8EF/Mlg2Dl6//WTcqFBeyZbHe+HwzWP33EIXpHdfwJCtWpfD/+ lvdDvI2DUrDUiMVcJwnYrWbRuHtdE/fjI0BtmYA01JL0Oe4+kxB3vS4MnlmH8ENc i7KThAEDdyrqeX1DTPmef1YTuhprGAB/pj2GYGe/93QDXMDOPMG3pvYm6Up02MzD a2UNL/JvCEQloABXFyIM =/lXQ -----END PGP SIGNATURE----- Merge tag 'iommu-fixes-v4.13-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull IOMMU fix from Joerg Roedel: "Another fix, this time in common IOMMU sysfs code.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
