Mauro Carvalho Chehab ccfdcb325f ABI: sysfs-bus-soundwire-slave: use wildcards on What definitions 
An "N" upper letter is not a wildcard, nor can easily be identified
by script, specially since the USB sysfs define things like.
bNumInterfaces. Use, instead, <N>, in order to let script/get_abi.pl
to convert it into a Regex.

Description: SoundWire Slave status

	These properties report the Slave status, e.g. if it
	is UNATTACHED or not, and in the latter case show the
	device_number. This status information is useful to
	detect devices exposed by platform firmware but not
	physically present on the bus, and conversely devices
	not exposed in platform firmware but enumerated.
