[PATCH] ASoC: intel: fix build when ACPI is not enabled

[Randy Dunlap <rdunlap@infradead.org>]

From: Randy Dunlap <rdunlap@infradead.org>

kconfig tools generate the following warning when CONFIG_ACPI is not
enabled:

warning: (SND_SOC_INTEL_BYTCR_RT5640_MACH && SND_SOC_INTEL_BYTCR_RT5651_MACH && SND_SOC_INTEL_CHT_BSW_RT5672_MACH && SND_SOC_INTEL_CHT_BSW_RT5645_MACH && SND_SOC_INTEL_CHT_BSW_MAX98090_TI_MACH) selects SND_SST_IPC_ACPI which has unmet direct dependencies (SOUND && !M68K && !UML && SND && SND_SOC && ACPI)

causing these build errors:

In file included from ../sound/soc/intel/atom/sst/sst_acpi.c:40:0:
../include/acpi/acpi_bus.h:65:20: error: conflicting types for 'acpi_evaluate_dsm'
 union acpi_object *acpi_evaluate_dsm(acpi_handle handle, const u8 *uuid,
In file included from ../sound/soc/intel/atom/sst/sst_acpi.c:31:0:
../include/linux/acpi.h:676:34: note: previous definition of 'acpi_evaluate_dsm' was here
 static inline union acpi_object *acpi_evaluate_dsm(acpi_handle handle,

I am told that ACPI is a requirement for these drivers, so make that
explicit. Also end help text sentences with a period.

Should SND_SOC_INTEL_SST and possibly other similar drivers get this
same change?
