Subject: Re: [PATCH] driver: usb: nullify dangling pointer in cdc_ncm_free


So I am afraid I have to ask again, whether anybody sees a fundamental
issue with the new version attached patch, as opposed to it not being an
elegant
solution?

I corrected the stuff Johan found and split the method in the asix driver.

I do not understand smsc95xx well, so I left it in the current state.
