From 8a7eab2b54b349d005181fd971cfa027b1976c7b Mon Sep 17 00:00:00 2001 From: David Howells Date: Wed, 2 Jan 2013 15:13:02 +0000 Subject: [PATCH] UAPI: Strip _UAPI prefix on header install no matter the whitespace Commit 56c176c9cac9 ("UAPI: strip the _UAPI prefix from header guards during header installation") strips the _UAPI prefix from header guards, but only if there's a single space between the cpp directive and the label. Make it more flexible and able to handle tabs and multiple white space characters.
