[PATCH] usb: gadget: u_ether: remove obnoxious warning messages

[Alvin Šipraga]

From: Alvin Šipraga <alsi@bang-olufsen.dk>

There is really no need for the driver to unconditionally emit warnings
like this on every usage:

[    6.967283] using random self ethernet address
[    6.967294] using random host ethernet address

Since this is normal behaviour, just remove the messages altogether.

Please see the thread at:
	https://lore.kernel.org/r/20230116155545.101391-1-jonathanh@nvidia.com

for more details.

This should use dev_warn() or better yet, just dev_dbg().

thanks,
