Subject: [PATCH 1/2] intel-rst: Use ACPI_FAILURE() macro instead !ACPI_SUCCESS() for error checking
Date: Wed, 17 Sep 2014 00:13:55 +0300	[thread overview]
Message-ID: <1410902036-10282-2-git-send-email-peter.ujfalusi@gmail.com> (raw)
In-Reply-To: <1410902036-10282-1-git-send-email-peter.ujfalusi@gmail.com>

ACPI_SUCCESS is defined as:
#define ACPI_SUCCESS(a)			(!(a))

There is no need for the the double ! since there is already a macro
defined for failures: ACPI_FAILURE()
