With current implementation, communication between interface driver and
upper mdss encoder layer are implemented through function calls. This
increase code complexity. Since struct msm_display_info contains msm
generic display information, it can be expended to contains more useful
information, such as widebus and dcs, in future to serve as communication
channel purpose between interface driver and upper mdss encoder layer so
that existing function calls can be eliminated.
This patch more struct msm_display_info to msm_drv.h to be visible by
whole msm scope.

So in the structure you're "moving" there's this member called "dsc".

...but then when you "move" the structure to its new location, which
should be a noop, then <poof> the "dsc" variable vanishes (along with
the kernel doc description of it before the structure).
Sorry, i did not resolve the conflicts correctly when i cherry-pick
them to msm-next tree.
Will fix them.
