Subject: [PATCH 4.14 13/39] gpiolib: acpi: Turn dmi_system_id table into a generic quirk table
Date: Tue, 14 Jan 2020 11:01:47 +0100
Message-ID: <20200114094342.117512030@linuxfoundation.org> (raw)
In-Reply-To: <20200114094336.210038037@linuxfoundation.org>

From: Hans de Goede <hdegoede@redhat.com>

commit 1ad1b54099c231aed8f6f257065c1b322583f264 upstream.

Turn the existing run_edge_events_on_boot_blacklist dmi_system_id table
into a generic quirk table, storing the quirks in the driver_data ptr.

This is a preparation patch for adding other types of (DMI based) quirks.
