Subject: [PATCH] staging: vc04_services: no need to save the log debufs dentries
Git-commit: 3b93c0f4b6accb8105152900d7e414593a8b0c79
Patch-mainline: v4.18-rc1
References: FATE#324827
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.
