Thanks for the email. It has been refined recently, the code can be found here:

Hello there, linux-4.15-rc1/drivers/gpu/drm/i915/gvt/cmd_parser.c:1640]: (style) Checking if unsigned variable 'bb_size' is less than zero. Source code is /* get the size of the batch buffer */ bb_size = find_bb_size(s); if (bb_size < 0) return -EINVAL; but static int find_bb_size(struct parser_exec_state *s) so the code isn't properly checking the return value. Suggest code rework. Regards David Binderman
