base: https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git for-next
config: i386-allmodconfig (attached as .config)
compiler: gcc-7 (Debian 7.3.0-1) 7.3.0
reproduce:
# save the attached .config to linux build tree
make ARCH=i386

All warnings (new ones prefixed by >>):

>> WARNING: drivers/spi/spi-renesas-rpc.o(.text+0xabd): Section mismatch in reference from the function rpc_spi_probe() to the variable .init.rodata:r8a7795es1
The function rpc_spi_probe() references
the variable __initconst r8a7795es1.
This is often because rpc_spi_probe lacks a __initconst
annotation or the annotation of r8a7795es1 is wrong.
