Historically, the legacy DAI naming scheme was applied to platform drivers and the newer scheme to CODEC drivers. During componentisation the core lost the knowledge of if a driver was a CODEC or platform, they were all now components. To continue to support the legacy naming on older platform drivers a flag was added to the snd_soc_component_driver structure, non_legacy_dai_naming, to indicate to use the new scheme and this was applied to all CODECs as part of the migration. However, a slight issue appears to be developing with respect to this flag being opt in for the non-legacy scheme, which presumably we want to be the primary scheme used. Many codec drivers appear to forget to include this flag: grep -l -r "snd_soc_component_driver" sound/soc/codecs/*.c | xargs grep -L "non_legacy_dai_naming" | wc 48 48 556 It would seem more sensible to change the flag to legacy_dai_naming making the new scheme opt out. As a first step this patch adds a new flag for this so that the users can be updated.
