[PATCH 2/2] drm/dp_mst: Replace seq_printf with seq_puts for constant strings

[liuqiangneo]

From: Qiang Liu <liuqiang@xxxxxxxxxx>

Replace seq_printf() with seq_puts() when printing constant strings
without format specifiers. This is more efficient as seq_puts()
doesn't need to parse the format string.
