Subject: drm/qxl: fix cursor position with non-zero hotspot
From: John Keeping <john@xxxxxxxxxxxx>
commit d59a1f71ff1aeda4b4630df92d3ad4e3b1dfc885 upstream.
The SPICE protocol considers the position of a cursor to be the location
of its active pixel on the display, so the cursor is drawn with its
top-left corner at "(x - hot_spot_x, y - hot_spot_y)" but the DRM cursor
position gives the location where the top-left corner should be drawn,
with the hotspot being a hint for drivers that need it.
This fixes the location of the window resize cursors when using Fluxbox
with the QXL DRM driver and both the QXL and modesetting X drivers.
