[Spice-devel] [spice-server 1/3] Remove unneeded rcc->priv->latency_monitor.timer checks

[Christophe Fergeau]

red_channel_client_start_ping_timer(), red_channel_client_cancel_ping_timer(),
red_channel_client_restart_ping_timer() are no-ops when
rcc->priv->latency_monitor.timer is NULL, so there is no need to
explicitly check it's not NULL before calling these functions.
