tracing: Constify struct event_trigger_ops
'event_trigger_ops mwifiex_if_ops' are not modified in these drivers. Constifying these structures moves some data to a read-only section, so increase overall security, especially when the structure holds some function pointers. On a x86_64, with allmodconfig, as an example: Before: ====== text data bss dec hex filename 31368 9024 6200 46592 b600 kernel/trace/trace_events_trigger.o After: ===== text data bss dec hex filename 31752 8608 6200 46560 b5e0 kernel/trace/trace_events_trigger.o Cc: Masami Hiramatsu <mhiramat@kernel.org> Cc: Mathieu Desnoyers <mathieu.desnoyers@efficios.com> Link: https://lore.kernel.org/66e8f990e649678e4be37d4d1a19158ca0dea2f4.1741521295.git.christophe.jaillet@wanadoo.fr Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Steven Rostedt (Google) <rostedt@goodmis.org>
