rv/include: set variable 'da_mon_##name' to static

[PATCH -next v2] rv/include: set variable 'da_mon_##name' to static

Posted by Yu Liao 2 years, 3 months ago

gcc with W=1 reports
kernel/trace/rv/monitors/wip/wip.c:20:1: sparse: sparse: symbol 'da_mon_wip' was not declared. Should it be static?

The per-cpu variable 'da_mon_##name' is only used in its defining file, so
it should be static.
