Subject: drm/sti: use seq_puts to display a string
Git-commit: adea1db2ad3c8a26ffd5b39196b3b376dc861b82
Patch-mainline: v4.13-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

gdp_dbg_ctl() uses seq_printf() to display a color format name even
though there is no format string. When using -Wformat-string, gcc
reports the following warning:

    drivers/gpu/drm/sti/sti_gdp.c: In function 'gdp_dbg_ctl':
    drivers/gpu/drm/sti/sti_gdp.c:150:18: warning: format not a string
    literal and no format arguments [-Wformat-security]
        seq_printf(s, gdp_format_to_str[i].name);
                      ^~~~~~~~~~~~~~~~~

Silence this warning by using seq_puts() instead.
