[PATCH 5.10 159/575] most: fix control-message timeouts

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Date: 2021-11-15 19:27:33
Also in: lkml

From: Johan Hovold <johan@kernel.org>

commit 63b3e810eff65fb8587fcb26fa0b56802be12dcf upstream.

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")
