Subject: [PATCH] cgroup: Replace a seq_printf() call by seq_puts() in
 cgroup_print_ss_mask()

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

A string which did not contain a data format specification should be put
into a sequence. Thus use the corresponding function “seq_puts”.

This issue was detected by using the Coccinelle software.
