Subject: [PATCH 03/18] drm_property: change strncpy+truncation to strlcpy
Date: Fri, 13 Jul 2018 03:25:16 +0200 [thread overview]
Message-ID: <1531445116-19150-1-git-send-email-asmadeus@codewreck.org> (raw)
In-Reply-To: <1531444483-17338-1-git-send-email-asmadeus@codewreck.org>
Using strlcpy fixes this new gcc warning:
drivers/gpu/drm/drm_property.c: In function ‘drm_property_create’:
drivers/gpu/drm/drm_property.c:125:2: warning: ‘strncpy’ specified bound 32 equals destination size [-Wstringop-truncation]
strncpy(property->name, name, DRM_PROP_NAME_LEN);
