Hey guys,

For some reason, this commit led to the intel ddx leaking a LOT of RAM 
(600MB/s) on my machine when booting a recent version of plasma5 (kde). 
It does not happen on the modesetting driver.

Still have a few things to address before being able to investigate (the 
other issue I already reported to Michel being one of them).
