Subject: [2/2] USB: iuu_phoenix: drop redundant input-speed re-encoding
Date: Mon, 16 Jul 2018 13:51:56 +0200	[thread overview]
Message-ID: <20180716115156.29106-2-johan@kernel.org> (raw)

Drop redundant input-speed re-encoding at every open(). The output and
input speeds are initialised to the same value and are kept in sync on
termios updates.
