+Subject: [PATCH] staging: vboxvideo: Fix reporting invalid
+ suggested-offset-properties
+
+The x and y hints receives from the host are unsigned 32 bit integers and
+they get set to -1 (0xffffffff) when invalid. Before this commit the
+vboxvideo driver was storing them in an u16 causing the -1 to be truncated
+to 65535 which, once reported to userspace, was breaking gnome 3.26+
+in Wayland mode.
+
+This commit stores the host values in 32 bit variables, removing the
+truncation and checks for -1, replacing it with 0 as -1 is not a valid
+suggested-offset-property value. Likewise the properties are now
+initialized to 0 instead of -1, since -1 is not a valid value.
+This fixes gnome 3.26+ in Wayland mode not working with the vboxvideo
+driver.
