[PATCH] Register tty_devclass before use

[PATCH] Register tty_devclass before use

[Russell King]

Hi,

The following patch (against vanilla 2.5.64) registers the tty devclass
with sysfs before any drivers can use it - sysfs requires structures to
be registered before use.

The patch applies to bk-curr with offset.
