Subject: [PATCH v2 1/6] dell-led: remove GUID check from dell_micmute_led_set()
Date: Mon, 16 Jan 2017 14:21:59 +0100	[thread overview]
Message-ID: <20170116132204.6421-2-kernel@kempniu.pl> (raw)
In-Reply-To: <20170116132204.6421-1-kernel@kempniu.pl>

As dell_micmute_led_set() no longer uses the dell_wmi_perform_query()
method, which was removed in commit 0c41a08e131d ("dell-led: use
dell_smbios_send_request() for performing SMBIOS calls"), the
DELL_APP_GUID check is redundant and thus can be safely removed.
