From: Tristan Madani <tristan at talencesecurity.com>

This series adds missing bounds checks for firmware-controlled fields
in the Qualcomm wcn36xx driver.

Patch 1 prevents heap overflow from oversized HAL responses. Patch 2
validates PRINT_REG_INFO count. Patch 3 checks trigger BA response
length.

Changes in v3:
  - Regenerated from wireless-next with proper git format-patch.

Changes in v2:
  - No code changes from v1.

    indication
