Subject: [PATCH] acpi: Fix format string type mistakes
Date: Fri, 16 Dec 2016 13:51:37 -0800	[thread overview]
Message-ID: <20161216215137.GA96800@beast> (raw)

From: Emese Revfy <re.emese@gmail.com>

This adds the missing __printf attribute which allows compile time
format string checking (and will be used by the coming initify gcc
plugin). Additionally, this fixes the warnings exposed by the attribute.
