From: Mengdong Lin mengdong.lin@linux.intel.com
Rename the ABI struct and type because they are for configuring physical DAIs, not only backend DAIs since users may not need DPCM: - Rename struct snd_soc_tplg_be_dai to snd_soc_tplg_dai. - Rename type SND_SOC_TPLG_TYPE_BE_DAI to SND_SOC_TPLG_TYPE_DAI.
This code refactoring is backward compatible because: - Both layout of the struct and type value has no change. Kernel can find the same type value and map to same data layout. - This struct is not in ABI v4 used by user space atm.
