From ce8c0137001e3ac237830a6059addaee3b5e0e26 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Noralf=20Tr=C3=B8nnes?= Date: Thu, 23 Feb 2017 14:29:56 +0100 Subject: [PATCH] drm/tinydrm: mipi-dbi: Fix field width specifier warning MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This warning is seen on 64-bit builds in functions: 'mipi_dbi_typec1_command': 'mipi_dbi_typec3_command_read': 'mipi_dbi_typec3_command': >> drivers/gpu/drm/tinydrm/mipi-dbi.c:65:20: warning: field width specifier '*' expects argument of type 'int', but argument 5 has type 'size_t {aka long unsigned int}' [-Wformat=] DRM_DEBUG_DRIVER("cmd=%02x, par=%*ph\n", cmd, len, data); \ ^ include/drm/drmP.h:228:40: note: in definition of macro 'DRM_DEBUG_DRIVER' drm_printk(KERN_DEBUG, DRM_UT_DRIVER, fmt, ##__VA_ARGS__) ^~~ >> drivers/gpu/drm/tinydrm/mipi-dbi.c:671:2: note: in expansion of macro 'MIPI_DBI_DEBUG_COMMAND' MIPI_DBI_DEBUG_COMMAND(cmd, parameters, num); ^~~~~~~~~~~~~~~~~~~~~~ Fix by casting 'len' to int in the macro MIPI_DBI_DEBUG_COMMAND(). There is no chance of overflow.
