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. -- Cheers, Stephen Rothwell
