fbdev: fix snprintf() limit in show_bl_curve() The limit should be "PAGE_SIZE - len" instead of PAGE_SIZE. Also let's use scnprintf() because snprintf() returns the number of bytes which would have been printed if there were space and scnprintf() returns the number of bytes actually printed. I don't think we are ever going to actually hit this limit in real life. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
