From: Tristan Madani <tristan at talencesecurity.com>

This series adds missing bounds checks for firmware-controlled fields
in the Marvell libertas driver.

Patch 1 validates pkt_ptr offset in the RX path. Patch 2 checks
bssdescriptsize in scan responses.

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

Changes in v2:
  - No code changes from v1.
