The current code checks the first device on a link and assumes that all the other devices on the link will have the same endpoint aggregation status and endpoint group ID.
Say for example a system looked like:
SDW0 - Amp 1 (Aggregated, Group 1), Mic 1 (Aggregated, Group 2) SDW1 - Amp 2 (Aggregated, Group 1), Mic 2 (Aggregated, Group 2)
The current code would create the DAI link for the aggregated amps, although it is worth noting that the only reason Mic 2 is not added is the additional check that aborts processing the link when the device changes. Then when processing the DAI link for the microphones, Mic 2 would not be added, as the check will only be done on the first device, which would be Amp 2 and thus the wrong group, causing the whole link to be skipped.
Move the endpoint check to be for each device rather than the first device on each link.
