Subject: [PATCH 4.9 43/62] USB: serial: whiteheat: fix line-speed endianness
Date: Mon, 4 Nov 2019 22:45:05 +0100 [thread overview]
Message-ID: <20191104211947.080300933@linuxfoundation.org> (raw)
In-Reply-To: <20191104211901.387893698@linuxfoundation.org>
From: Johan Hovold <johan@kernel.org>
commit 84968291d7924261c6a0624b9a72f952398e258b upstream.
Add missing endianness conversion when setting the line speed so that
this driver might work also on big-endian machines.
Also use an unsigned format specifier in the corresponding debug
message.
