Merge tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk driver fixes from Stephen Boyd:
"An assortment of vendor specific clk drivers fixes, most notably
fallout from adding Tegra210 and rockchip rk3036/rk3368 drivers this
cycle.
There's also the random smattering of sparse/checker fixes, a build
"fix" to get the Tango clk driver to compile because the Kconfig
symbol was renamed after the fact, and a clk gpio fix for a patch
mismerge"
