[PATCHv2 0/2] Enable pre-allocated buffer support for driver_data

[yi1 . li]

From: Yi Li <yi1.li@xxxxxxxxxxxxxxx>

This series enables the equivalent pre-allocated buffer feature in 
request_firmware_into_buf to driver_data API, so caller can allocate
firmware data buffer and pass to driver_data. This will be used for
streaming support of driver_data, which allow caller to manage the size
and buffer of firmware streaming. 

Changes in v2:

  - Rebase to Luis R. Rodriguez's 20170501-driver-data-try2
    branch 
  - Move alloc_buf and alloc_buf_size to public driver_data_req_params
    structure.
  - Add self test cases.

Yi Li (2):
  firmware: Enable pre-allocated buffer support in driver_data
  test: add pre-allocated buffer to driver_data tester
