Yeah the BOSC0200 patch cannot go upstream as is, that will break the
orientation quirks in hwdb on:

[hans@...lem systemd]$ grep BOSC0200 hwdb/60-sensor.hwdb | wc -l
17
[hans@...lem systemd]$

At least 17 different models laptops / 2-in-1s

Patches 1-5, 7-13 and 15 are:

Reviewed-by: Hans de Goede <hdegoede@...hat.com>

I will send separate replies to:

[PATCH v1 06/15] i2c: acpi: Assign fwnode for devices created via i2c_acpi_new_device()
[PATCH v1 14/15] ACPI / scan: Create platform device for BOSC0200 ACPI nodes

Which are both a NACK from me (in their current state) because they both will
cause regressions.

Regards,

Hans
