From: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx> The comment above nc_vendor_write() suggests that the function could become async so that is usable in `in_interrupt()' context or that it already is safe to be called from such a context. Eitherway: The function did not become async since v2.4.9.2 (2002) and it must be not be called from `in_interrupt()' context because it sleeps on mutltiple occations. Remove the misleading comment.
