Subject: USB: serial: cypress_m8: fix interrupt-out transfer length
Date: Sun, 30 Sep 2018 18:03:11 +0200 [thread overview]
Message-ID: <20180930160311.32569-1-johan@kernel.org> (raw)
Fix interrupt-out transfer length which was being set to the
transfer-buffer length rather than the size of the outgoing packet.
Note that no slab data was leaked as the whole transfer buffer is always
cleared before each transfer.
Fixes: 9aa8dae7b1fa ("cypress_m8: use usb_fill_int_urb where appropriate")
Signed-off-by: Johan Hovold <johan@kernel.org>
