   4 Subject: [PATCH] wifi: ath11k: mhi: add a warning message for MHI_CB_EE_RDDM
   5  crash
   6
   7 Currently, the ath11k driver does not print a crash signature when a
   8 MHI_CB_EE_RDDM crash happens. Checked by triggering a simulated crash using the
   9 command and checking dmesg for logs:
  10
  11 echo assert > /sys/kernel/debug/ath11k/../simulate_fw_crash
  12
  13 Add a warning when firmware crash MHI_CB_EE_RDDM happens.

  15 Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.23
