[ Upstream commit e3f60e7e1a2b451f538f9926763432249bcf39c4 ]
All the entities must have a unique name. We can have a descriptive and
unique name by appending the function and the entity->id.
This is even resilent to multi chain devices.
Fixes v4l2-compliance:
Media Controller ioctls:
fail: v4l2-test-media.cpp(205): v2_entity_names_set.find(key) != v2_entity_names_set.end()
test MEDIA_IOC_G_TOPOLOGY: FAIL
fail: v4l2-test-media.cpp(394): num_data_links != num_links

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.
