Daniel Vetter fb740cf249 drm: Create drm_send_event helpers
Use them in the core vblank code and exynos/vmwgfx drivers.

Note that the difference between wake_up_all and _interruptible in
vmwgfx doesn't matter since the only waiter is the core code in
drm_fops.c. And that is interruptible.

v2: Adjust existing kerneldoc too.

Daniel Vetter 7142a348e7 drm/exynos: Use the new event init/free functions
Also fixes a bug in IPP with not correctly checking/allocating for
space in the event space. Not a too serious bug since it's not a
real ringbuffer, just a limit to avoid too much kernel allocations.

Beata Michalska e44bf6b7a5 drm/exynos/ipp: Validate buffer enqueue requests
As for now there is no validation of incoming buffer
enqueue request as far as the gem buffers are being
concerned. This might lead to some undesired cases
when the driver tries to operate on invalid buffers
(wiht no valid gem object handle i.e.).
Add some basic checks to rule out those potential issues.
