Subject: [for-next][PATCH 03/20] rv/monitors: add static qualifier for local symbols

From: Zeng Heng <zengheng4@...wei.com>

The sparse tool complains as follows:

kernel/trace/rv/monitors/wwnr/wwnr.c:18:19:
warning: symbol 'rv_wwnr' was not declared. Should it be static?

The `rv_wwnr` symbol is not dereferenced by other extern files,
so add static qualifier for it.

So does wip module.

Fixes:	8812d21219b9 ("rv/monitor: Add the wip monitor skeleton created by dot2k")
