Subject: [PATCH] wifi: ath11k: mhi: add a warning message for MHI_CB_EE_RDDM
crash
Currently, the ath11k driver does not print a crash signature when a
MHI_CB_EE_RDDM crash happens. Checked by triggering a simulated crash using the
command and checking dmesg for logs:
echo assert > /sys/kernel/debug/ath11k/../simulate_fw_crash
Add a warning when firmware crash MHI_CB_EE_RDDM happens.
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.23
