We can probably create a simple script that goes through commits,
collects their "upstream" commit ids, and searches linux-next for
Fixes: xxx... So we'd have simple way of checking if we are missing
any fixes.

If Renesas could submit b5881b153bc8 ("spi: spi-mem: Make 
spi_mem_default_supports_op() static inline") for 4.19-cip, it would
be nice :-).

Best regards,
