Subject: [PATCH] ocfs2: Combine two seq_printf() calls into one call in
 ocfs2_dlm_seq_show()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 13 Jan 2018 16:36:51 +0100

Some data were printed into a sequence by two separate function calls.
Print almost the same data by a single function call instead.
(Omit a tab character at the line end within a format string.)

This issue was detected by using the Coccinelle software.
