Subject: [PATCH v2] xmon: Use __printf markup to silence compiler
Date:   Sun, 25 Mar 2018 11:06:47 +0200
Message-Id: <20180325090648.1029-1-malat@debian.org>
In-Reply-To: <20180316110224.12260-2-malat@debian.org>

Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Update the other prototype declarations in asm/xmon.h.

Silence warnings (triggered at W=1) by adding relevant __printf attribute.
Move #define at bottom of the file to prevent conflict with gcc attribute.

Solve the original warning:

  arch/powerpc/xmon/nonstdio.c:178:2: error: function might be possible candidate for ‘gnu_printf’ format attribute [-Werror=suggest-attribute=format]

In turn this uncovered the following (partial list) warnings (treated as
errors with W=1):

  arch/powerpc/xmon/xmon.c:2866:17: error: format ‘%x’ expects argument of type ‘unsigned int’, but argument 2 has type ‘unsigned char *’ [-Werror=format=]
