Subject: [PATCH 4/5] staging/lustre/obdclass: Combine two seq_printf() calls
 into one call in lprocfs_rd_state()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 1 Jan 2017 16:26:36 +0100

Some data were printed into a sequence by two separate function calls.
Print the same data by a single function call instead.

This issue was detected by using the Coccinelle software.
