Subject: [RESEND PATCH v3 1/3] drivers/clocksource/timer-of: Remove __init markings

From: Saravana Kannan <saravanak@...gle.com>

This allows timer drivers to be compiled as modules which can be a
platform-level devices, so the timer_of_init()/_cleanup() should able to
be called from platform_driver_register() which support deferred probing.
