Linux kernel source tree
215afa89d2
PCI/TSM, the PCI core functionality for the PCIe TEE Device Interface Security Protocol (TDISP), has a need to walk all subordinate functions of a Device Security Manager (DSM) to setup a device security context. A DSM is physical function 0 of multi-function or SR-IOV device endpoint, or it is an upstream switch port. In error scenarios or when a TEE Security Manager (TSM) device is removed it needs to unwind all established DSM contexts. Introduce reverse versions of PCI device iteration helpers to mirror the setup path and ensure that dependent children are handled before parents.

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.
