Subject: [TTY] Register tty devclass before use.
X-Git-Tag: v2.5.65~30^2
X-Git-Url: http://git.neil.brown.name/?a=commitdiff_plain;h=c4ab9d7892e7f3bf3698f514c8db8f5e719f2b66;p=history.git

[TTY] Register tty devclass before use.

Register the tty devclass with sysfs before tty drivers initialise -
sysfs requires structures to be registered before use.  This is
required for the previous serial csets, as well as any drivers which
are initialising using __initcall() or module_init().
