Subject: [PATCH v2 02/32] acpi-video-detect: Remove the unused acpi_video_dmi_demote_vendor() function
Date: Fri, 12 Jun 2015 13:23:21 +0200	[thread overview]
Message-ID: <1434108231-12323-3-git-send-email-hdegoede@redhat.com> (raw)
In-Reply-To: <1434108231-12323-1-git-send-email-hdegoede@redhat.com>

Remove the now unused acpi_video_dmi_demote_vendor() function, this was
never a proper counter part of acpi_video_dmi_promote_vendor() since
the calls to acpi_video_dmi_promote_vendor() are not counted.
