stable: gpu: drm: sti: gdp: Please back-port this patch into v4.11

[Lee Jones]

Dear Stable Maintainers,

2f410f88c0a1 drm/sti: fix GDP size to support up to UHD resolution

Without this patch 20% of a large monitor screen is artificially clipped
when running on STMicroelectronics' STiH410-B2260.  This is important to
rectify in v4.11.x since that is the kernel version Fedora 26 will be
released on.  Apart from this BUG, the STiH410-B2260 is otherwise fully
supported in F26 -- the next version isn't due for release for another
8 months.

This patch should be added to Stable Kernel Version 4.11.

Kind regards,
Lee

Just 4.11?  What about older kernels as well?

Also, fedora is known to take bug fixes in their kernel, no rush for
something like this :)

Fedora F26 will be released using one of the v4.11.x kernels
(whichever version is current at the end of June I believe).  Taking
this patch into v4.11.x now ensures that the B2260 will work great
out-of-the-box.  Taking it later will ensure that it does not.  The
user will have to `dnf update` (or whatever tom-foolery Fedora uses
these days ;) ) in order to obtain the fix.  The former scenario is
preferred.
