Merge branch 'for_3.16/clk_fixes_non_critical' of git://git.kernel.org/pub/scm/linux/kernel/git/tfiga/samsung-clk into v3.16-next/clk-samsung

Pull Samsung clock non-critical fixes from Tomasz Figa:

"This pull requests contains a number of non-critical fixes for Samsung clock
framework and drivers, including:

1) a series of fixes for Exynos5420 to correct clock definitions and make the
driver closer to the documentation,

2) several missing clocks and clock IDs added to Exynos4, Exynos5250 and
Exynos5420 drivers,

3) fix for incorrect initialization of clock table with NULL,

4) compiler warning fix."
