Subject: [PATCH 02/15] wifi: ath11k: print debug level in debug messages
Date: Fri,  9 Jun 2023 17:24:27 +0300	[thread overview]
Message-ID: <20230609142440.24643-3-kvalo@kernel.org> (raw)
In-Reply-To: <20230609142440.24643-1-kvalo@kernel.org>

From: Kalle Valo <quic_kvalo@quicinc.com>

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
