Subject: [PATCH 4/6] staging: vc04_services: remove struct vchiq_debugfs_info

From: [email-masked] (Greg Kroah-Hartman)
Date: Fri, 1 Jun 2018 13:10:02 +0200

This structure, and the one static variable that was declared with it,
were not being used for anything.  The log_categories field was being
set, but never used again.  So just remove it entirely as it is not
needed at all.
