To make it easier understand the context of a debug message print the debug level before the actual message. An example: [21867.231900] ath11k_pci 0000:06:00.0: wmi processed regulatory ext channel list The tracepoint call is not modified, it's better to userspace print the debug level if needed. Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.23 Signed-off-by: Kalle Valo <quic_kvalo@quicinc.com> Link: https://lore.kernel.org/r/20230609142440.24643-3-kvalo@kernel.org
