Message-ID: <20161112032914.hg24zqqlkwirxx7z@hotbox> MIME-Version: 1.0 Content-Disposition: inline User-Agent: NeoMutt/20161014 (1.7.1) Sender: linux-acpi-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-acpi@vger.kernel.org X-Virus-Scanned: ClamAV using ClamSMTP The Dell Latitude 3350's ethernet card attempts to use a reserved IRQ (18), resulting in ACPI being unable to enable the ethernet. This patch forces a specific _REV (ACPI revision) value as a workaround to allow the Dell Latitude 3350's board to work correctly. The approach is similar to 18d78b64fddc11eb336f01e46ad3303a3f55d039 Signed-off-by: Michael Pobega --- drivers/acpi/blacklist.c | 12 ++++++++++++ 1 file changed, 12 insertions(+) diff --git a/drivers/acpi/blacklist.c b/drivers/acpi/blacklist.c index bdc67ba..05cd61f 100644 --- a/drivers/acpi/blacklist.c +++ b/drivers/acpi/blacklist.c @@ -160,6 +160,18 @@ static struct dmi_system_id acpi_rev_dmi_table[] __initdata = { DMI_MATCH(DMI_PRODUCT_NAME, "XPS 13 9343"), }, }, + /* + * Resolves a quirk with the Dell Latitude 3350 that + * causes the ethernet adapter to not function. + */ + { + .callback = dmi_enable_rev_override, + .ident = "DELL Latitude 3350", + .matches = { + DMI_MATCH(DMI_SYS_VENDOR, "Dell Inc."), + DMI_MATCH(DMI_PRODUCT_NAME, "Latitude 3350"), + }, + }, #endif {} };
