Mario Limonciello 24867516f0 ACPI: OSI: Remove Linux-Dell-Video _OSI string
This string was introduced because drivers for NVIDIA hardware
had bugs supporting RTD3 in the past.

Before proprietary NVIDIA driver started to support RTD3, Ubuntu had
had a mechanism for switching PRIME on and off, though it had required
to logout/login to make the library switch happen.

When the PRIME had been off, the mechanism had unloaded the NVIDIA
driver and put the device into D3cold, but the GPU had never come back
to D0 again which is why ODMs used the _OSI to expose an old _DSM
method to switch the power on/off.

That has been fixed by commit 5775b843a6 ("PCI: Restore config space
on runtime resume despite being unbound"). so vendors shouldn't be
using this string to modify ASL any more.

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 Restructured Text 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.
