Ugh, I misread that again. No, mipi_dsi_packet::size is NOT claimed to
contain both TX and RX. It just says "size of the packet", and packet
clearly does not hold the RX data anyway. I don't know what's
happening to my reading comprehension...

But the mismatch on whether drivers implement these correctly and
whether any callers actually care about the documented semantics still
stands.
