From: Tristan Madani <tristan@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.
