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.
