All the waiting sync in the downstream divers are try to fix special 
problems,

and some of them inherited from upstream vop driver, for example: the 
fb_unref_work,

It submitted by Tomas Figa to upstream vop driver to make the wait for 
flip and asynchronously cursor work

right.

VOP2 share the same hardware design in vblank, so I don't think these 
code are useless.
