[PATCH ath-next v3 0/2] wifi: ath12k: accept what newer QCN9274 firmware requests at boot

QCN9274 firmware WLAN.WBE.1.6-01243 requests two things at boot that
ath12k does not implement: a target memory segment of type 0xa (AFC)
and direct buffer rings for module IDs 2 and 3. Neither is needed for
operation. Today the first gets a wrong answer and the second aborts
the parse of the service ready ext event.

Patch 1 answers every unsupported memory type with size 0. Patch 2
skips unknown ring module IDs instead of failing the parse. Both keep
a warning, so the gap between firmware and driver stays visible.

v3:
- 1/2: clear the size in the default case, no AFC case; keep the
  warning; describe only the response change (Rameshkumar Sundaram).
- 2/2: warn for a skipped entry instead of a debug message.
- Rebased on ath-next.

v2:
- 1/2: do not allocate the region, answer with size 0 (Rameshkumar
  Sundaram); former 3/3 dropped.
- 2/2: commit message and comment reworded.

v2: https://lore.kernel.org/r/20261102200235.48973-1-gsustek@gmail.com
v1: https://lore.kernel.org/r/20261030220836.14164-1-gsustek@gmail.com

Goran Sustek (2):
  wifi: ath12k: report size 0 for unsupported target memory types
  wifi: ath12k: skip unknown direct buffer ring module IDs
