Subject: [PATCH v2] powerpc/mm/radix: use do/while(0) trick for single statement block
Date: Mon, 23 Apr 2018 21:36:38 +0200	[thread overview]
Message-ID: <20180423193638.10535-1-malat@debian.org> (raw)
In-Reply-To: <20180408194424.8719-1-malat@debian.org>

In commit 7a22d6321c3d ("powerpc/mm/radix: Update command line parsing for
disable_radix") an `if` statement was added for a possible empty body
(prom_debug).

Fix the following warning, treated as error with W=1:

  arch/powerpc/kernel/prom_init.c:656:46: error: suggest braces around empty body in an ‘if’ statement [-Werror=empty-body]

Suggested-by: Randy Dunlap <rdunlap@infradead.org>
