Re: [PATCH] USB: usb_wwan: Fix urb leak in usb_wwan_close()

Hi Johan,

Sorry for the very late reply. Thank you for the review.

You are right that the drain loop leaks the reference taken by
usb_get_from_anchor(), and the same leak is in usb_wwan_submit_delayed_urbs().
I see you fixed both in c78dd373b5c5 ("USB: serial: usb_wwan: fix urb leak on
disconnect"), which is in mainline and has already been queued for stable, so
I am not resending either patch and patchwork 14822918 and 14822924 can be
dropped.

How this was found and fixed is described in my reply to the sierra patch; I
have not repeated it here.

I am going through the remaining feedback by hand now and will not post
patches in bulk again.

Thanks,
Wentao
