Subject: [PATCH v2 0/2] Fix s5p-mfc lock contention in request firmware paths
Date: Fri,  3 Nov 2017 20:01:56 -0600	[thread overview]
Message-ID: <cover.1509760483.git.shuahkh@osg.samsung.com> (raw)

This patch series fixes inefficiencies and lock contention in the request
firmware paths.

Changes since v2:
- Addressed Andre's review comments. Removed fw_buf->virt null check
  as it is not needed. Removed handling s5p_mfc_load_firmware() from
  probe routine. Simply try loading in case it works.

  media: s5p-mfc: fix lock confection - request_firmware() once and keep
    state
