Jiri Slaby bf9c1fca9a Char: nozomi, set tty->driver_data appropriately ... Sorry, one more fix, this one depends on the other, so this is rather 2/2. -- tty->driver_data is used all over the code, but never set. This results in oopses like: BUG: unable to handle kernel NULL pointer dereference at 0000000000000130 IP: [<ffffffff814a0040>] mutex_lock+0x10/0x40 ...
