linux-next: build failure after merge of the net-next tree

Hi all,

After merging the net-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/usb/class/cdc-wdm.c: In function 'wdm_wwan_port_stop':
drivers/usb/class/cdc-wdm.c:858:2: error: implicit declaration of function 'kill_urbs' [-Werror=implicit-function-declaration]
  858 |  kill_urbs(desc);
      |  ^~~~~~~~~

Caused by commit

  cac6fb015f71 ("usb: class: cdc-wdm: WWAN framework integration")

kill_urbs() was removed by commit

  18abf8743674 ("cdc-wdm: untangle a circular dependency between callback and softint")

Which is included in v5.13-rc1.

I have used the net-next tree from next-20210511 for today.
