[PATCH] clk: sunxi: fix overflow when setting up divided factors

[Emilio López]

Currently, we are allocating space for two pointers, when we actually
may need to store three of them (two divisors plus the original clock).
Fix this, and change sizeof(type) to sizeof(*var) to keep checkpatch.pl
happy.

Hi Mike,

Is there any chance you can include this oneliner on your second part of
the pull request to Linus?

Cheers,

Emilio
