With the upcoming NTP correction related rate adjustments to be implemented in the clockevents core, the latter needs to get informed about every rate change of a clockevent device made after its registration. Currently, em_sti violates this requirement in that it registers its clockevent device with a dummy rate and sets its final rate through clockevents_config() called from its ->set_state_oneshot(). This patch moves the setting of the clockevent device's rate to its registration. I checked all current em_sti users in arch/arm/mach-shmobile and right now, none of them changes any rate in any clock tree relevant to em_sti after their respective time_init(). Since all em_sti instances are created after time_init(), none of them should ever observe any clock rate changes. - Determine the ->rate value in em_sti_probe() at device probing rather than at first usage. - Set the clockevent device's rate at its registration. - Although not strictly necessary for the upcoming clockevent core changes, set the clocksource's rate at its registration for consistency.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
