I feel like the "why" is missing.  This appears to start to explain how 
gem->open() might be useful for the driver, but does not seem to 
complete explaining the connection to the driver.  From the code 
changes, it looks like using gem->open() simplifies the code by 
allocating the vpu_addr in one place for all BOs.  If that is the goal, 
I feel that it should be mentioned here.
