From: Lucas Stach Date: Fri, 20 Oct 2017 15:46:55 +0000 (+0200) Subject: drm/etnaviv: short-circuit perfmon ioctls X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=330b52bd9bba1d66028772dfe08c053a34c5069a;p=linux.git drm/etnaviv: short-circuit perfmon ioctls The feature implementation isn't stable yet. Reject any attempt to use the IOCTLs for now. This keeps most of the code in place, so we can stabilize it in-tree, but keeps userspace from using the feature for now.
