No, I'm not. usb_control_msg_recv() is an API that was recently
introduced, and get_registers() in rtl8150.c was also modified to
use it in order to prevent partial reads.
By your tree, I assume you mean
(it was the only one I could find).
I don't see the commit that this patch is supposed to fix in your
tree either... :/
Nonetheless, this commit fixes an issue that was applied to the
networking tree, and has made its way into linux-next as well, if
I'm not mistaken.

The script I've been using for sending patches in had been configured to CC
the maintainer(s) and respective mailing list(s). Sorry about that.
I will put the relevant maintainer in the To: field, fix the Fixes tag, and
mark the patch as [PATCH net] as well and send in a v2.
Thank you for your time.
