[PATCH] scripts/get_abi.pl: more strict matching of [XYZ]

[David Lechner]

When using `scripts/get_abi.pl undefined --search-string=iio` to try to
find undocumented ABI's in the IIO subsystem, no matches were found.

This was due to the fact that we have documented a directory naming
pattern:

	What: /sys/bus/iio/devices/iio:deviceX

which gets translated to the regex

	/sys/.*/iio\:device.*

which matches everything under every iio:device directory, causing any
attributes below this directory to incorrectly be filtered out as
already documented.

This patch makes the matching more strict by changing the replacement
for [XYZ] from .* to [^/]* so that we don't match the directory
separator. This way documenting directories won't filter out everything
contained in the directory as already being documented.

get_maintainers.pl didn't pick up any matches for this patch, so I guess
this would go through the kbuild tree? (Since MAINTAINERS says:
"KERNEL BUILD + files below scripts/ (unless maintained elsewhere)")
