Date: Mon, 19 Oct 2026 14:20:15 +0000 [thread overview]
Message-ID: <sashiko-outbox-177350@kernel.org> (raw)
In-Reply-To: <20261019135441.1420968-112-sashal@kernel.org>
> From: Yousef Alhouseen <alhouseenyousef@gmail.com>
>
> [ Upstream commit 8c9c5b9a689612dcb92a04a4218c975cd19f19d8 ]
>
> set_carrier() ignores the result of the USB control transfer and tests
> the stack variable supplied as its receive buffer. If the device rejects
> or aborts the request, that variable remains uninitialized and the driver
> chooses an arbitrary carrier state.
>
> Leave the existing carrier state unchanged when the link status cannot be
> read. A transient USB error should not be treated as link loss.
