Merge branch 'drm-intel-fixes-2' of ssh://master.kernel.org/pub/scm/linux/kernel/git/ickle/drm-intel into drm-fixes
* 'drm-intel-fixes-2' of ssh://master.kernel.org/pub/scm/linux/kernel/git/ickle/drm-intel: (30 commits) drm/i915: Prevent uninitialised reads during error state capture drm/i915: Use consistent mappings for OpRegion between ACPI and i915 drm/i915: Handle the no-interrupts case for UMS by polling drm/i915: Disable high-precision vblank timestamping for UMS drm/i915: Increase the amount of defense before computing vblank timestamps drm/i915,agp/intel: Do not clear stolen entries Remove MAYBE_BUILD_BUG_ON BUILD_BUG_ON: make it handle more cases module: fix missing semicolons in MODULE macro usage param: add null statement to compiled-in module params module: fix linker error for MODULE_VERSION when !MODULE and CONFIG_SYSFS=n module: show version information for built-in modules in sysfs selinux: return -ENOMEM when memory allocation fails tpm: fix panic caused by "tpm: Autodetect itpm devices" TPM: Long default timeout fix trusted keys: Fix a memory leak in trusted_update(). keys: add trusted and encrypted maintainers encrypted-keys: rename encrypted_defined files to encrypted trusted-keys: rename trusted_defined files to trusted drm/i915: Recognise non-VGA display devices ...
