In Android before 2018-04-05 or earlier security patch level on Qualcomm Snapdragon Automobile and Snapdragon Mobile SD 820 and SD 820A, the input to RPMB write response function is a buffer from HLOS that needs to be authenticated (using HMAC) and then processed.

The function will return various types of errors depending on the values of the `response` and `result` fields of the buffer before verifying the HMAC tag.
