Subject: [patch 22/35] net: usb: net1080: Remove in_interrupt() comment
Date: Sun, 27 Sep 2020 21:49:08 +0200 [thread overview]
Message-ID: <20200927194922.057018859@linutronix.de> (raw)
In-Reply-To: 20200927194846.045411263@linutronix.de
From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
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.
