perf: Mark expected switch fall-through
In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.
This patch fixes the following warning:
kernel/events/core.c: In function ‘perf_event_parse_addr_filter’:
kernel/events/core.c:9154:11: warning: this statement may fall through [-Wimplicit-fallthrough=]
kernel = 1;
~~~~~~~^~~
kernel/events/core.c:9156:3: note: here
case IF_SRC_FILEADDR:
^~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
