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

Takashi Iwai (6): ALSA: core: Use READ_ONCE() / WRITE_ONCE() for power state change ALSA: control: Track in-flight control read/write/tlv accesses ALSA: control: Drop superfluous snd_power_wait() calls ALSA: control: Minor optimization for SNDRV_CTL_IOCTL_POWER_STATE ALSA: Drop superfluous argument from snd_power_wait() ALSA: pcm: Block the release until the system resume finishes
Now all patches merged to topic/pci-rescan-v2 branch, and into for-next branch. The former is a branch freshly based on 5.13-rc1, so that other trees may pull cleanly.
