ASoC: pcm512x: Do not redefine DIV_ROUND_CLOSEST_ULL

From: Fabio Estevam <[email protected]>

DIV_ROUND_CLOSEST_ULL is already defined at <linux/kernel.h>, so use the definition from this header file rather than re-defining it locally.

This fixes the following build warning:

sound/soc/codecs/pcm512x.c:34:0: warning: "DIV_ROUND_CLOSEST_ULL" redefined [enabled by default] In file included from include/linux/list.h:8:0,

                 from include/linux/module.h:9,
                 from sound/soc/codecs/pcm512x.c:19:

include/linux/kernel.h:110:0: note: this is the location of the previous definition

Someone already sent a patch for this, unfortunately the issue exists only in -mm and akpm didn' pick the patch up yet.
