[PATCH 3.10 36/44] scripts/kernel-doc: dont eat struct members with __aligned

From: Johannes Berg <johannes.berg@intel.com>

commit 7b990789a4c3420fa57596b368733158e432d444 upstream.

The change from \d+ to .+ inside __aligned() means that the following
structure:

struct test {
u8 a __aligned(2);
u8 b __aligned(2);
};

essentially gets modified to

struct test {
u8 a;
};

for purposes of kernel-doc, thus dropping a struct member, which in
turns causes warnings and invalid kernel-doc generation.

Fix this by replacing the catch-all (".") with anything that's not a
semicolon ("[^;]").
