[PATCH 3/9] drm/i915: Replace 14 seq_printf() calls by seq_puts()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Thu, 4 May 2017 13:20:47 +0200

Some strings which did not contain data format specifications should be put
into a sequence. Thus use the corresponding function "seq_puts".

This issue was detected by using the Coccinelle software.
