Subject: [PATCH net-next 7/9] s390/qeth: add __printf format attribute to qeth_dbf_longtext
Date: Mon, 25 Oct 2021 11:56:56 +0200	[thread overview]
Message-ID: <20211025095658.3527635-8-jwi@linux.ibm.com> (raw)
In-Reply-To: <20211025095658.3527635-1-jwi@linux.ibm.com>

From: Heiko Carstens <hca@linux.ibm.com>

Allow the compiler to recognize and check format strings and parameters.

As reported with allmodconfig and W=1:

drivers/s390/net/qeth_core_main.c: In function ‘qeth_dbf_longtext’:
drivers/s390/net/qeth_core_main.c:6190:9: error: function ‘qeth_dbf_longtext’ might be a candidate for ‘gnu_printf’ format attribute [-Werror=suggest-attribute=format]
 6190 |         vsnprintf(dbf_txt_buf, sizeof(dbf_txt_buf), fmt, args);
      |         ^~~~~~~~~
