Subject: [PATCH v2 0/2] can: add Transmitter Delay Compensation (TDC)
 documentation

TDC was added to the kernel in 2021 but I never took time to update
the documentation. The year is now 2025... As we say: "better late
than never"!

The first patch is a small clean up which fixes an incorrect statement
concerning the CAN DLC, the second patch is the real thing and adds
the documentation of how to use the ip tool to configure the TDC.

  - Fix below "make htmldocs" error:

  - Change from "Bullet lists" to "Definition lists" format.
