Subject: linux-next: build failure after merge of the pm tree

Hi Rafael,

After merging the pm tree, today's linux-next build (powerpc allyesconfig)
failed like this:

drivers/devfreq/tegra-devfreq.c: In function 'tegra_devfreq_target':
drivers/devfreq/tegra-devfreq.c:500:2: error: implicit declaration of function 'clk_set_min_rate' [-Werror=implicit-function-declaration]
  clk_set_min_rate(tegra->emc_clock, rate);
  ^

Caused by commit

  797da5598f3a ("PM / devfreq: Add COMPILE_TEST for build coverage")

clk_set_min_rate() usage depends on CONFIG_HAVE_CLK.

I added the following for today:
