Subject: [PATCH 0/3] firmware: selftest for request_firmware_into_buf
Date: Thu, 15 Aug 2019 17:09:42 -0700
Message-ID: <20190816000945.29810-1-scott.branden@broadcom.com> (raw)

This patch series adds kernel selftest of request_firmware_into_buf.
The API was added to the kernel previously untested.

Also included in this patch series is a fix for a race condition
discovered while testing request_firmware_into_buf.  Mutex may
not be correct final solution but demonstrates a fix to a race
condition new test exposes.

Scott Branden (3):
  test_firmware: add support for request_firmware_into_buf
  selftest: firmware: Add request_firmware_into_buf tests
  firmware: add mutex fw_lock_fallback for race condition
