Here is the third version of dynamic debug improvements in Venus
driver.  As has been suggested on previous version by Joe [1] I've
made the relevant changes in dynamic debug core to handle leveling
as more generic way and not open-code/workaround it in the driver.

About changes:
 - added change in the dynamic_debug and in documentation
 - added respective pr_debug_level and dev_dbg_level

Honestly, this seems like you want to use tracepoints, not dynamic debug.

Also see this patch series:

[PATCH 00/16] dynamic_debug: cleanups, 2 features

It adds/expands dynamic debug flags quite a bit.
