[PATCH] ASoC: rt5660: remove double const

[PATCH] ASoC: rt5660: remove double const

[Nicholas Mc Guire]

Drop the const qualifier as it is being added by SOC_ENUM_DOUBLE_DECL()
already which is called by SOC_ENUM_SINGLE_DECL() here.

Fixes: commit 2b26dd4c1fc5 ("ASoC: rt5660: add rt5660 codec driver")

sparse throws the warning:
sound/soc/codecs/rt5660.c:529:14: warning: duplicate const 
sound/soc/codecs/rt5660.c:532:14: warning: duplicate const 

this is due to:
static const SOC_ENUM_SINGLE_DECL(rt5660_if1_dac_enum,...

which via:
#define SOC_ENUM_SINGLE_DECL(name, xreg, xshift, xtexts) \
        SOC_ENUM_DOUBLE_DECL(name, xreg, xshift, xshift, xtexts)

expands to:
#define SOC_ENUM_DOUBLE_DECL(name, xreg, xshift_l, xshift_r, xtexts) \
        const struct soc_enum name = SOC_ENUM_DOUBLE(xreg, xshift_l, xshift_r, \
                                                ARRAY_SIZE(xtexts), xtexts)
and that already carries the const qualifier so that results in the
"duplicate const" from sparse. The fix is simply to drop the first
const.

Patch was compile tested with: x86_64_defconfig + CONFIG_COMPILE_TEST=y
SND_SOC=m + SND_SOC_ALL_CODECS=m (implies SND_SOC_RT5660=m)

Patch is aginast 4.10-rc3 (localversion-next is next-20170112)
