[PATCH v4 0/4] firmware: encapsulate firmware loading status

[Daniel Wagner <wagi@monom.org>]

From: Daniel Wagner <daniel.wagner@bmw-carit.de>

Hi,

This is version depends on Luis' '[PATCH v4 0/5] firmware: add SmPL
grammar to avoid issues' series [1]. Because of that I was able to get
rid of loading_timeout and firmware_loading_timeout() in the
!FW_LOADER_USER_HELPER_FALLBACK case.

cheers,
daniel

This series depends on
[1] http://marc.info/?l=linux-kernel&m=147320896231418&w=2

changes since v3:
  - added 'firmware: Move umh locking code into
    fw_load_from_user_helper()'
  - dropped loading_tiemout and firmware_loading_time() for
    !CONFG_FW_LOADER_USER_HELPER
  - rebased on Luis patches

changes since v2:
  - more splitting out
    - first patch factors out all the bit ops into fw_status
    - second patch gets rid of the bit ops
    - third get rid of fw_lock by using swait

changes since v1:
  - moved swait change into its own patch
  - added ifdef section for FW_LOADER_USER_HELPER_FALLBACK
  - updated commit message highlighting the mutex usage drop a bit
