Date: Wed, 19 Jul 2017 13:15:45 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Cyril Bur <cyrilbur@...il.com>, Joe Perches <joe@...ches.com>, Andrew Morton <akpm@...ux-foundation.org>, Linus Torvalds <torvalds@...ux-foundation.org> Subject: [PATCH 3.18 17/28] checkpatch: silence perl 5.26.0 unescaped left brace warnings 3.18-stable review patch. If anyone has any objections, please let me know. ------------------ From: Cyril Bur <cyrilbur@...il.com> commit 8d81ae05d0176da1c54aeaed697fa34be5c5575e upstream. As of perl 5, version 26, subversion 0 (v5.26.0) some new warnings have occurred when running checkpatch. Unescaped left brace in regex is deprecated here (and will be fatal in Perl 5.30), passed through in regex; marked by <-- HERE in m/^(.\s*){ <-- HERE \s*/ at scripts/checkpatch.pl line 3544. Unescaped left brace in regex is deprecated here (and will be fatal in Perl 5.30), passed through in regex; marked by <-- HERE in m/^(.\s*){ <-- HERE \s*/ at scripts/checkpatch.pl line 3885. Unescaped left brace in regex is deprecated here (and will be fatal in Perl 5.30), passed through in regex; marked by <-- HERE in m/^(\+.*(?:do|\))){ <-- HERE / at scripts/checkpatch.pl line 4374. It seems perfectly reasonable to do as the warning suggests and simply escape the left brace in these three locations.
