[PATCH 0/3] ALSA: ctxfi: Clean up DAIO resource allocation

[Harin Lee]

Clean up the resource allocation in atc_get_resources() and related
functions, on top of the recent SPDIFI1 fixes.

The earlier refactoring introduced a kernel crash on hw20k2, where
daio_device_index() returned -EINVAL for the SPDIFI1 type and the
value was used as an unsigned array offset. On my development system
(64G memory), this did not manifest as a crash, making the bug
difficult to catch during testing.

Tested on the real hw20k2 hardware with mem=8G to verify the original
crash and confirm these patches.

Harin Lee (3):
  ALSA: ctxfi: Rename SPDIFI1 to SPDIFI_BAY
  ALSA: ctxfi: Use matching DAIO type for da_desc
  ALSA: ctxfi: Precompute SRC allocation loop bound
