6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hayes Wang <hayeswang@xxxxxxxxxxx>
commit 95a4c1d617b92cdc4522297741b56e8f6cd01a1e upstream.
After commit ec51fbd1b8a2 ("r8152: add USB device driver for
config selection"), the code about changing USB configuration
in rtl_vendor_mode() wouldn't be run anymore. Therefore, the
function could be removed.
