Subject: [PATCH 1/6] lockdep: Replace 11 seq_puts() calls by seq_putc()
Date: Wed, 03 May 2017 20:36:50 +0000	[thread overview]
Message-ID: <0fae17e0-1880-e041-293e-8ab3184df6a7@users.sourceforge.net> (raw)
In-Reply-To: <3f95acb5-c037-b6fa-7a9b-258b4ae465fb@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 3 May 2017 21:00:26 +0200

Some single characters should be put into a sequence.
Thus use the corresponding function "seq_putc".

This issue was detected by using the Coccinelle software.
