Subject: [PATCH] ACPI-EC: Delete an unnecessary check before the function call "acpi_ec_delete_query"
Date: Sun, 15 Nov 2015 22:52:30 +0100	[thread overview]
Message-ID: <5648FE9E.5060201@users.sourceforge.net> (raw)
In-Reply-To: <5317A59D.4@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 15 Nov 2015 22:42:27 +0100

The acpi_ec_delete_query() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
