Subject: [PATCH 383/454] staging: vc04_services: move client dbg directory
into static variable
commit 24e8d3fc42f25936ff270e404847a3a462c38468 upstream
This does not need to be part of a wrapper function, or in a structure,
just properly reference it directly as a single variable.
The whole variable will be going away soon anyway, this is just a step
toward that direction.
