[RFC PATCH 1/2] ASoC: lm49453: fix useless assignment before return

[Pierre-Louis Bossart]

Cppcheck warning:

sound/soc/codecs/lm49453.c:1210:11: style: Variable 'pll_clk' is
assigned a value that is never used. [unreadVariable]

  pll_clk = BIT(4);
          ^

FIXME: What is the correct fix?
	/* fll clk slection */
	pll_clk = BIT(4);
	return 0;

is the assignment redundant or the 'return 0' a mistake?
