Subject: [PATCH v2] md-multipath: Use seq_putc() in multipath_status()

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

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

This issue was detected by using the Coccinelle software.
