Subject: [PATCH v2 0/2] Fix s5p-mfc lock contention in request firmware paths

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.

Shuah Khan (2):
  media: s5p-mfc: remove firmware buf null check in
    s5p_mfc_load_firmware()
  media: s5p-mfc: fix lock confection - request_firmware() once and keep
    state
