Subject: [PATCH] SCRIPTS: Correct RE in header CONFIG leak check.
Date: Sun, 10 May 2009 11:45:04 -0400 (EDT) [thread overview]
Message-ID: <alpine.LFD.2.00.0905101141140.17364@localhost.localdomain> (raw)
Correct the regular expression in scripts/headers_check.pl to include
'_' as a valid character in the class; otherwise, the check will
report a "leaked" symbol of CONFIG_A_B_C as merely CONFIG_A.
