Subject: [PATCH AUTOSEL 5.4 15/16] platform/x86: asus-wmi: Ignore fan on E410MA

From: Thomas Weißschuh <linux@...ssschuh.net>

[ Upstream commit 82cc5c6c624c63f7b57214e325e2ea685d924e89 ]

The ASUS VivoBook has a fan device described in its ACPI tables but does
not actually contain any physical fan.
Use the quirk to inhibit fan handling.
