[PATCH 5.18 0175/1095] ACPI: video: Use native backlight on Dell Inspiron N4010

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

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

[ Upstream commit 03c440a26cba6cfa540d65924e9db86fcea362b2 ]

The Dell Inspiron N4010 does not have ACPI backlight control,
so acpi_video_get_backlight_type()'s heuristics return vendor as
the type to use.

But the vendor interface is broken, where as the native (intel_backlight)
works well, add a quirk to use native.
