cppcheck warnings:

sound/soc/codecs/wm8903.c:1552:11: style: Variable 'best_val' is
assigned a value that is never used. [unreadVariable]
 best_val = ((clk_sys * 10) / bclk_divs[0].ratio) - bclk;

sound/soc/codecs/wm8903.c:1559:12: style: Variable 'best_val' is

  best_val = cur_val;

Indeed what matters in the code is the blck_div, the best_val is
assigned but never tested or used.
