[PATCH v2 0/2] Rework clk/vt8500 wm8650_find_pll_bits()

[Roman Volkov <v1ron@mail.ru>]

From: Roman Volkov <rvolkov@v1ros.org>

Hi Arnd, Stephen,

This patch finally removes the warnings from GCC about possibly uninitialized
variables 'best_div2', 'best_div1', and 'best_mul'. Also one of the functions
is reworked, so that the algorithm is much easier. This is to continue the
work started in [1].

This code is tested on WM8650. Also the testing app was used in user-mode to
check possible values and performance [2].

Please schedule this for 4.8.

Changes in v2:
Apply WM8650 fix on top of changes by Arnd [3].

Thanks,
