[PATCH 0/3] ALSA: qc_audio_offload: address space cleanups

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

I ran into a build time warning and spent some time trying to
gently rewrite the new driver to avoid the warning and make it
behave more like other drivers.

I'm still a bit confused about what the driver actually does
and why a buffer has to be mapped into a two devices, but I hope
that either my patches clear this up enough, or if they are wrong
are helpful to have someone else sort it out properly.

The patches are currently queued for v6.16 in Greg's usb-next
tree, so my fixes look correct, I hope he can apply them there
before the merge window.

Arnd Bergmann (3):
  ALSA: qc_audio_offload: rename dma/iova/va/cpu/phys variables
  ALSA: qc_audio_offload: avoid leaking xfer_buf allocation
  ALSA: qc_audio_offload: try to reduce address space confusion
