USB: ftdi_sio.c: Allow setting latency timer on FT232RL
The new FT232RL allows setting and getting the value of the latency timer, like on the FT232BM. However, the driver will not create the sysfs entries for the RL without this one-line patch. I have tested it on two systems with successful results. From: Stepan Moskovchenko <stevenm86@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
