Subject: [PATCH] MD-RAID: Use seq_putc() in three status functions

From: Markus Elfring <elfring@...rs.sourceforge.net>

A single character (a closing square bracket) should be put into a sequence
at the end in these functions.
Thus use the corresponding function "seq_putc".

This issue was detected also by using the Coccinelle software.
