X-Git-Tag: v4.5-rc1~20^2~24^2~13^2~15
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=caf94ed8629afb82d61a82ce76fb314145933a40;p=platform%2Fkernel%2Flinux-exynos.git

ASoC: Intel: bytcr_rt5640: fixup DAI codec_name with HID

Codec name is hard-coded in machine driver, pass information
from actual ACPI HID to help support BIOS variations
