Subject: [PATCH] most: fix control-message timeouts
Date: Mon, 25 Oct 2021 13:58:11 +0200 [thread overview]
Message-ID: <20211025115811.5410-1-johan@kernel.org> (raw)
USB control-message timeouts are specified in milliseconds and should
specifically not vary with CONFIG_HZ.
Use the common control-message timeout defines for the five-second
timeouts.
Fixes: 97a6f772f36b ("drivers: most: add USB adapter driver")
Cc: stable@vger.kernel.org # 5.9
