Some drivers don't have real ->create_handle callbacks. - cirrus/ast/mga200: Returns either 0 or -EINVAL. - udl: Didn't even bother with a callback, leading to a nice userspace-triggerable OOPS. - vmwgfx: This driver bothered with an implementation to return 0 as the handle (which is the canonical no-obj gem handle). All have in common that ->create_handle doesn't really make too much sense for them - that ioctl is used only for seamless fb takeover in the radeon/nouveau/i915 ddx drivers. So allow drivers to not implement this and return a consistent -ENODEV. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> |
