Hi, this is a series of patches for addressing the remaining problem with the implicit fb sync. The first one is to cover the left over EP run state at re-configuring PCM. The second one is a workaround for a regression with the hw constraints, and the last one is the refactoring and fix for the multiple EPs assigned in the format list.
