From 4b63539bb2f604b26ef4951c5c14828d24a7ce6c Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 8 Sep 2015 13:56:26 +0200 Subject: [PATCH] drm: Define a drm_invalid_op ioctl implementation MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit And use it in radeon to replace all the ioctls no longer valid in kms mode. I plan to also use this later on when nuking the ums support for i915. Note that setting the function pointer in the ioctl table to NULL would amount to the same, but that results in some debug output from the drm_ioctl() function. I've figured it's cleaner to have a special-purpose function.
