[PATCH] memory: renesas-rpc-if: Add missing static keyword

[Biju Das]

Fix the below sparse warnings:
 symbol 'rpcif_impl' was not declared. Should it be static?
 symbol 'xspi_impl' was not declared. Should it be static?

Did you test now your code with sparse and smatch? Otherwise I will wait
for more reports.

Yes, I tested with the instructions in [1] and the patch fixes the above issues.

I meant other issues. So you did not test with smatch? That's your task
and you should not rely on the community to provide such tests/checks
instead.

Please run standard kernel tools for static analysis, like coccinelle,
smatch and sparse, and fix reported warnings. Also please check for
warnings when building with W=1 for gcc and clang. Most of these
commands (checks or W=1 build) can build specific targets, like some
directory, to narrow the scope to only your code. The code here looks
like it needs a fix. Feel free to get in touch if the warning is not clear.

Krzysztof

OK got it. will run these jobs in our local CI.
