Subject: [PATCH net v2] net: wwan: Fix missing net device name for error message print
Date: Fri, 26 Apr 2024 17:24:44 +0800	[thread overview]
Message-ID: <20240426092444.825735-1-slark_xiao@163.com> (raw)

In my local, I got an error print in dmesg like below:
"sequence number glitch prev=487 curr=0"
After checking, it belongs to mhi_wwan_mbim.c. Refer to the usage
of this net_err_ratelimited() API in other files, I think we
should add net device name print before message context.

Fixes: aa730a9905b7 ("net: wwan: Add MHI MBIM network driver")
