Hi, This patchset is a part of patches to reserve/release isochronous resources in pcm.hw_params/hw_free callbacks, like posted patchsets below: https://mailman.alsa-project.org/pipermail/alsa-devel/2019-June/150118.html https://mailman.alsa-project.org/pipermail/alsa-devel/2019-June/150863.html However, in this patchset, I focus on code refactoring, due to kernel API implementation in firewire-lib. The target devices supported by ALSA bebob, fireworks and oxfw drivers implements Connection Management Procedure (CMP) in IEC 61883-1. For CMP, the drivers use kernel API in firewire-lib. This API has private data including the data for isochronous resources, and its implementation is tightly-coupled to maintenance of isochronous resources. This patchset is a preparation for future work to change the CMP implementation.
