Focusrite Saffire 6 has fixed audioformat quirks with multiple endpoints assigned to a single altsetting. Unfortunately the generic parser couldn't detect the sync endpoint correctly as the implicit sync due to the missing EP attribute bits. In the former kernels, it used to work somehow casually, but it's been broken for a while after the large code change in 5.11. This patch cures the regression by the following: - Allow the static quirk table to provide the sync EP information; we just need to fill the fields and let the generic parser skipping parsing if sync_ep is already set. - Add the sync endpoint information to the entry for Saffire 6.
