Subject: [PATCH 008/008] [RESUBMIT2] USB: serial: suppress log entry
From: Elina Pasheva <epasheva@xxxxxxxxxxxxxxxxxx>
The following is summary of changes we have made to sierra.c driver in
[PATCH 008/008] from the series dealing with improving urb handling:
- Suppress an entry in logs by not re-submitting an urb when usb_submit_urb()
returns -EPERM, as this shows that usb_kill_urb() is running
(as suggested by Oliver Neukum )
