Subject: [PATCH] arch: x86: platform: mrst: pr_err() need notice that 'sdev->modalias'
 may not a NUL terminated string.


According to the areas which use "%16.16s" within this file, the
'sdev->modalias' may not always be a NUL terminated string.

So need use "%.16s" instead of "%s" in pr_err(), or may cause issue.
