Subject: [PATCH 3/4] MIPS/kernel/proc: Replace 28 seq_printf() calls by seq_puts() in show_cpuinfo()
Date: Mon, 24 Oct 2016 14:29:57 +0200	[thread overview]
Message-ID: <33b51bd8-7225-55a5-4be8-d062390e6f67@users.sourceforge.net> (raw)
In-Reply-To: <3809e713-2f08-db60-92c1-21d735a4f35b@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 24 Oct 2016 13:45:04 +0200

Strings which did not contain data format specifications should be put
into a sequence.

* Thus use the corresponding function "seq_puts" so that the data output
  will be a bit more efficient.

* Omit the format string "%s" which became unnecessary with this refactoring.


This issue was detected by using the Coccinelle software.
