[PATCH v2 0/6] ALSA: Prep work for PCI rescan support

[Takashi Iwai]

Hi,

this is a revised patch set as a prep work for the future-planned PCI
rescan support(*).  The essential part is the patch to track in-flight
tasks, and the rest are cleanups and fixes in the core code.  With
those changes, the driver can perform a sort of software suspend on
the device without the hardware intervention, which is required during
the PCI BAR movement, for example.

v1->v2:
* Move / drop unnecessary snd_power_wait() calls
* Rephrase changelogs and comments, reorder patches
