Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux
53c7626356
This patch allows SerDev module to manage serial devices declared as attached to an UART in ACPI table. acpi_serdev_add_device() callback will only take into account entries without enumerated flag set. This flags is set for all entries during ACPI scan, except for SPI and I2C serial devices, and for UART with 2nd patch in the series. Check if a serdev device as been allocated during acpi_walk_namespace() to prevent serdev controller registration instead of the tty-class device.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
