From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
If the 'kmalloc()' fails, we need to undo the previous
'dbc_alloc_request()' call.
Because of the more similar function name, it is more logical to use
'dbc_free_request()' instead of 'xhci_dbc_free_req()'.
Both are equivalent here because:
static void xhci_dbc_free_req(struct dbc_ep *dep, struct dbc_request *req)
{
kfree(req->buf);
dbc_free_request(dep, req);
}
and 'req->buf' is known to be NULL at this point
