Series staging: vc04_services: Clarify bulk 'userdata' usage | expand

Commit Message

Umang Jain Oct. 23, 2024, 11:04 a.m. UTC
In a previous commit, struct vchiq_bulk 'userdata' got renamed to
'cb_data' since it is the data pointer passed in
VCHIQ_BULK_CALLBACK_MODE's callback. Since struct vchiq_completion_data*
structs also has 'bulk_userdata' for completion records, rename
'bulk_userdata' member to 'cb_data' for these structs as well.

This brings consistency and clarity for the struct members. No
functional change in this patch.
