Subject: [PATCH v2 0/3] wireless: fix division by zero in USB drivers

This series adds the missing endpoint sanity checks to the wireless USB
drivers that were doing packet-size calculations without first making
sure that the USB descriptors were sane.

Johan

Changes in v2:
 - tighten the sanity checks for the mwifiex firmware-download mode to
   handle also a missing bulk-out endpoint (noticed by Brian Norris)


Johan Hovold (3):
  ath10k: fix division by zero in send path
  ath6kl: fix division by zero in send path
  mwifiex: fix division by zero in fw download path
