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, no tests existed for existing request_firmware_into_buf kernel API. Therefore tests have been created and submitted upstream here: "[PATCH v2 0/2] firmware: selftest for request_firmware_into_buf" https://lkml.org/lkml/2019/8/22/1367 The firmware selftests patches here require those patches to be applied first in order for the firmware selftest patches in this series to be valid. Finally, in this patch series is the addition of a new Broadcom Valkyrie driver utilizing the new request_firmware_into_buf enhanced API.
