Did you base your patches on purpose on -rc6?
mtd/next is based on -rc2.
Not a big deal, but can cause confusion.

5de15b610f78 ("mtd: hyperbus: add Renesas RPC-IF driver") does not build here
with CONFIG_COMPILE_TEST because the driver needs functions from CONFIG_RENESAS_RPCIF
which is only buildable for CONFIG_ARCH_RENESAS.

This should do the trick, please double check:

Anyway, pulled. :-)
