    9 The code in drmmode_set_cursor does not properly handle the case where
    10 drmModeSetCursor2 returns any other error than EINVAL and silently fails to set
    11 a cursor.
    12
    13 So only return when the drmModeSetCursor2 succeeds (i.e returns 0) and disable
    14 the cursor2 usage on EINVAL.
