[alsa-devel] [PATCH RFT] ASoC: wm2200: Fix setting dai format in wm2200_set_fmt

According to the defines in wm2200.h:
/*
 * R1284 (0x504) - Audio IF 1_5
 */
#define WM2200_AIF1_FMT_MASK                    0x0007  /* AIF1_FMT - [2:0] */
#define WM2200_AIF1_FMT_SHIFT                        0  /* AIF1_FMT - [2:0] */
#define WM2200_AIF1_FMT_WIDTH                        3  /* AIF1_FMT - [2:0] */

We should not left shift 1 bit for fmt_val when setting dai format.

Hi Mark,
wm2200.h defines WM2200_AIF1_FMT_SHIFT to be 0, so current code looks wrong to me.
I don't have the datasheet, so can you check if this patch is correct?
