Dan Carpenter dd5a74f2f9 drm/radeon: integer underflow in radeon_cp_dispatch_texture()
The test:

	if (size > RADEON_MAX_TEXTURE_SIZE) {

"size" is an integer and it's controled by the user so it can be
negative and the test can underflow.  Later we use "size" in:

	dwords = size / 4;
	...
	RADEON_COPY_MT(buffer, data, (int)(dwords * sizeof(u32)));

It causes memory corruption to copy a negative size buffer.
