3.16.51-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Jonas Gorski <jonas.gorski@xxxxxxxxx> commit 1b495faec231980b6c719994b24044ccc04ae06c upstream. Make the behaviour of clk_get_rate consistent with common clk's clk_get_rate by accepting NULL clocks as parameter. Some device drivers rely on this, and will cause an OOPS otherwise. Fixes: e7300d04bd08 ("MIPS: BCM63xx: Add support for the Broadcom BCM63xx family of SOCs.")
