Subject: cli: static keyword tweak
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6cd8912f102e721ea10ac13a1885fb9127cb4951;p=project%2Fubus.git

cli: static keyword tweak

Function ubus_cli_listen() is called only once, and function uloop_run()
and uloop_done() which need struct ubus_event_handler listener are
called within this function, so it's not needed to mark struct
ubus_event_handler listener as static. The same as pointer struct
ubus_context *ctx in main function.

Global struct commands is only used in this file, so it should be marked
static.
