Subject: r8152 logs error `can't resubmit intr, status -1`

Dear Linux folks,

On the Dell XPS 13 9360/0596KF, BIOS 2.21.0 06/02/2022, with a USB-C 
Dell DA300 adapter attached to the only USB-C port on the left, Linux 
6.5.10 logged the message below:

      r8152 4-1.2:1.0 enx18dbf22dccf3: can't resubmit intr, status -1

As this is error log level, how can I fix it?

Trying to understand the code, does `-1` mean `NOPERM`?

     $ git grep EPERM include/uapi/asm-generic/errno-base.h
     #define	EPERM		 1	/* Operation not permitted */

Skimming the code this is returned by `usb_submit_urb()`, which in turn 
returns the return value of `usb_hcd_submit_urb()`. Do you have some 
debugging hints how to for example print the call trace for this case or 
enable more debug messages to understand the issue?

Kind regards,

Paul
