Subject: [PATCH] blk-mq: Use seq_puts() in __blk_mq_debugfs_rq_show()

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.
