Subject: [PATCH v2 0/7] firmware: add partial read support in request_firmware_into_buf

This patch series adds partial read support in request_firmware_into_buf.
In order to accept the enhanced API it has been requested that kernel
selftests and upstreamed driver utilize the API enhancement and so
are included in this patch series.

Also in this patch series is the addition of a new Broadcom VK driver
utilizing the new request_firmware_into_buf enhanced API.

Scott Branden (7):
  fs: introduce kernel_pread_file* support
  firmware: add offset to request_firmware_into_buf
  test_firmware: add partial read support for request_firmware_into_buf
  firmware: test partial file reads of request_firmware_into_buf
  bcm-vk: add bcm_vk UAPI
  misc: bcm-vk: add Broadcom VK driver
  MAINTAINERS: bcm-vk: add maintainer for Broadcom VK Driver
