[alsa-devel] [PATCH] ASoC: snd_soc_set_dmi_name will use DMI_SYS_VENDOR if available

[mengdong.lin at linux.intel.com]

From: Mengdong Lin <mengdong.lin at linux.intel.com>

This fix is based on Daniel Drake's suggestion: most x86 machines have a
meaningfull DMI_SYS_VENDOR rather than DMI_BOARD_VENDOR.

So snd_soc_set_dmi_name will try to get vendor name from DMI_SYS_VENDOR
at first, and if that's null, then use DMI_BOARD_VENDOR.
