Subject: [PATCH 0/4] firmware: cs_dsp: Add check to prevent overrunning the firmware file

This series fixes various missing length checks when processing
variable-length data from the firmware file. These could have
caused overrunning the end of firmware file buffer, or wild
pointer accesses.

Richard Fitzgerald (4):
  firmware: cs_dsp: Fix overflow checking of wmfw header
  firmware: cs_dsp: Return error if block header overflows file
  firmware: cs_dsp: Validate payload length before processing block
  firmware: cs_dsp: Prevent buffer overrun when processing V2 alg
    headers
