Framework Laptops' ACPI exposes the EC with id "PNP0C09". But "PNP0C09" is part of the ACPI standard; there are lots of computers with EC chips with this id, and most of them don't support the cros_ec protocol. The driver could find the ACPI device by having "PNP0C09" in the acpi_match_table, but this would match devices which don't support the cros_ec protocol. Instead, add a new quirk "CROS_EC_LPC_QUIRK_ACPI_ID" which allows the id to be specified. This quirk is applied after the DMI check shows that the device is supported. Tested-by: Dustin L.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
