Subject: [RFC v6 06/23] clockevents: make clockevents_config() static
Date: Fri, 9 Sep 2016 22:00:16 +0200 [thread overview]
Message-ID: <20160909200033.32103-7-nicstange@gmail.com> (raw)
In-Reply-To: <20160909200033.32103-1-nicstange@gmail.com>
A clockevent device's rate should be configured before or at registration
and changed afterwards through clockevents_update_freq() only.
For the configuration at registration, we already have
clockevents_config_and_register().
Right now, there are no clockevents_config() users outside of the
clockevents core.
To mitigiate the risk of drivers errorneously reconfiguring their rates
through clockevents_config() *after* device registration, make
clockevents_config() static.
