[PATCH 3.16 223/294] ASoC: adau1977: Fix truncation warning on 64 bit architectures

[Ben Hutchings]

3.16.50-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Mark Brown <broo...@linaro.org>

commit d8df26bb57d2a86365de46a5421b97417401e39a upstream.

Negating ADAU1977_BLOCK_POWER_SAI_LDO_EN creates an unsigned long constant
with all bits set which on 64 bit architectures needs to be truncated to
an unsigned int, generating a warning. Add an explicit cast since we know
this is OK.
