+Subject: [PATCH 386/454] staging: vc04_services: no need to save the log
+ debufs dentries
+
+commit 3b93c0f4b6accb8105152900d7e414593a8b0c79 upstream
+
+The log entry dentries are only set, never referenced, so no need to
+keep them around. Remove the pointer from struct
+vchiq_debugfs_log_entry as it is not needed anymore and get rid of the
+separate vchiq_debugfs_create_log_entries() function as it is only used
+in one place.
