From: Ben Skeggs Date: Sat, 9 Aug 2014 18:10:25 +0000 (+1000) Subject: drm/nouveau/fifo: audit and version fifo channel classes X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bbf8906b2cad17cf9530b06db7509d0e39b02d16;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git drm/nouveau/fifo: audit and version fifo channel classes The full object interfaces are about to be exposed to userspace, so we need to check for any security-related issues and version the structs to make it easier to handle any changes we may need in the future.
