[PATCH] Fix sysfs class support for CAPI

this patch fixes a bug in the CAPI TTY support, because the ->name value
of the TTY driver shouldn't contain a "/". After changing this there are
now a "capi20" TTY device and a "capi20" control device and so I renamed
the control device to "capi". The userspace visible part must be done by
udev and I added these two rules to restore the old namespace:

	# CAPI devices
	KERNEL="capi",          NAME="capi20", SYMLINK="isdn/capi20"
	KERNEL="capi*",         NAME="capi/%n"
