Subject: [PATCH 41/90] USB: ftdi_sio: fix initial baud rate
|
|
|
|
commit 108e02b12921078a59dcacd048079ece48a4a983 upstream.
|
|
|
|
Fix regression introduced by commit b1ffb4c851f1 ("USB: Fix Corruption
|
|
issue in USB ftdi driver ftdi_sio.c") which caused the termios settings
|
|
to no longer be initialised at open. Consequently it was no longer
|
|
possible to set the port to the default speed of 9600 baud without first
|
|
changing to another baud rate and back again.
