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

Hi all,

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

cc1: some warnings being treated as errors

Caused by commit

  a3047a81ba13 ("net: ethernet: ti: cpts: add support for ext rftclk selection")

of_clk_parent_fill() and others above are only available if
CONFIG_COMMON_CLK is set (which it is not for this build).

I have reverted that commit for today.
