  rv: Fix documentation reference in da_monitor.h (2026-01-12 07:44:09 +0100)

----------------------------------------------------------------
rv changes for v6.20 (for-next)

Summary of changes:

- Refactor da_monitor to minimise macros

  Complete refactor of da_monitor.h to reduce reliance on macros
  generating functions. Use generic static functions and uses the
  preprocessor only when strictly necessary (e.g. for tracepoint
  handlers).
  The change essentially relies on functions with generic names (e.g.
  da_handle) instead of monitor-specific as well adding the need to
  define constant (e.g. MONITOR_NAME, MONITOR_TYPE) before including the
  header rather than calling macros that would define functions.
  Also adapt monitors and documentation accordingly.

- Cleanup DA code generation scripts

  Clean up functions in dot2c removing reimplementations of trivial
  library functions (__buff_to_string) and removing some other unused
  intermediate steps.

- Annotate functions with types in the rvgen python scripts

- Remove superfluous assignments and cleanup generated code

  The rvgen scripts generate a superfluous assignment to 0 for enum
  variables and don't add commas to the last elements, which is against
  the kernel coding standards. Change the generation process for a
  better compliance and slightly simpler logic.

- Remove superfluous declarations from generated code

  The monitor container source files contained a declaration and a
  definition for the rv_monitor variable. The former is superfluous and
  was removed.

- Fix reference to outdated documentation
