Subject: [PATCH 2/7] kernel-trace: Replace five seq_puts() calls by seq_putc()
Date: Fri, 5 May 2017 23:02:31 +0200 [thread overview]
Message-ID: <d7f03e83-07f8-b8d8-9a22-41dceb5de174@users.sourceforge.net> (raw)
In-Reply-To: <3419381c-6a8f-f0f6-86e8-3ee7f9af0076@users.sourceforge.net>
From: Markus Elfring <elfring@users.sourceforge.net>

Five single characters should be put into a sequence.
Thus use the corresponding function "seq_putc".
This issue was detected by using the Coccinelle software.
