drm/tinydrm: mipi-dbi: Fix field width specifier warning
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. Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Signed-off-by: Dave Airlie <airlied@redhat.com>
