typo: regsiter -> register

Couldn't this instead be:

while (--i >= 0)
clk_unregister(clk_table[i]);

Since we only get here if all the clocks are registered properly and we
always register EXYNOS_AUDSS_MAX_CLKS clocks, couldn't this simply be:

for (i = 0; i < EXYNOS_AUDSS_MAX_CLKS; i++)
clk_unregister(clk_table[i]);

Otherwise the whole series looks good to me. Feel free to add:
