Date: Wed, 23 Dec 2020 19:21:16 -0800 From: Roland Dreier <roland@...nel.org> To: Oliver Neukum <oliver@...kum.org> Cc: netdev@...r.kernel.org, linux-usb@...r.kernel.org Subject: [PATCH] CDC-NCM: remove "connected" log message The cdc_ncm driver passes network connection notifications up to usbnet_link_change(), which is the right place for any logging. Remove the netdev_info() duplicating this from the driver itself. This stops devices such as my "TRENDnet USB 10/100/1G/2.5G LAN" (ID 20f4:e02b) adapter from spamming the kernel log with cdc_ncm 2-2:2.0 enp0s2u2c2: network connection: connected messages every 60 msec or so.
