[Spice-devel] [drm/qxl 6/6] qxl: Allow resolution which are not multiple of 8

[Christophe Fergeau]

The use of drm_cvt_mode() in qxl_add_monitors_config_modes() means that
the resolutions we are going to present to user-space are going to be
rounded down to a multiple of 8. In the QXL arbitrary resolution case,
this is not useful.
This commit forces the actual width/height that was requested by the
client in the drm_display_mode structure rather than keeping the
rounded version.

I know this is very hacky, but I have no idea what is important to be set in the mode struct,
if there is a better way to create it without getting the rounding to a multiple of 8, ...
