[Qemu-devel] [PATCH 21/29] vmsvga: Use AND mask bpp parameter in SVGA_CMD_DEFINE_CURSOR

[Liran Alon <liran.alon@oracle.com>]

From: Leonid Shatz <leonid.shatz@oracle.com>

Prefer variable names of cursor structure from VMware SVGA DevKit.
In addition, make sure to use the AND mask bpp parameter in
SVGA_CMD_DEFINE_CURSOR.
