   4 Subject: [PATCH 84/84] wifi: ath11k: Allow ath11k to boot without caldata in
   5  ftm mode
   6
   7 Currently, if ath11k is unable to load the calibration data file it will
   8 always exit. However the calibration data may not be present in factory
   9 test mode, so update the logic to allow the driver to execute in FTM mode
  10 even if downloading the calibration data fails.
