When building for 32-bit architectures, we get a harmless warning:

intel-ish-hid/ishtp-hid-client.c: In function 'process_recv':
intel-ish-hid/ishtp-hid-client.c:139:7: error: format '%lu' expects
argument of type 'long unsigned int', but argument 3 has type
'unsigned int' [-Werror=format=]

This changes the format string to print size_t variables using %zu
instead.
Is the ordering of patch correct?
ISH config depends on X86_64, so it would not be enabled for 32 bit
build.
So your patch 5/5 will adding "|| COMPILE_TEST", hence it is building.

Thanks,
