From: Kees Cook Date: Sat, 17 Dec 2016 01:02:32 +0000 (-0800) Subject: drm/amdgpu: use designated initializers X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=613e61a0252c54371c957d44767544a76f0da3a6;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/amdgpu: use designated initializers Prepare to mark sensitive kernel structures for randomization by making sure they're using designated initializers. These were identified during allyesconfig builds of x86, arm, and arm64, with most initializer fixes extracted from grsecurity.
