From: Tvrtko Ursulin Date: Mon, 13 Jul 2015 15:51:39 +0000 (+0100) Subject: drm/i915: Forward all core DRM ioctls to core compat handling X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ac7e7ab1c3243b10b41653cc8d8536088d83b152;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Forward all core DRM ioctls to core compat handling Previously only core DRM ioctls under the DRM_COMMAND_BASE were being forwarded, but the drm.h header suggests (and reality confirms) ones after (and including) DRM_COMMAND_END should be forwarded as well. We need this to correctly forward the compat ioctl for the botched-up addfb2.1 extension.
