Subject: [PATCH v1 0/3] Fix dpm_list ordering issue due to fw_devlink optimization

When commit 93d2e4322aa7 ("of: platform: Batch fwnode parsing when
adding all top level devices") enabled batch processing of fw_devlink to
optimize the parsing time, it caused a suspend/resume regression due to
the use of deferred probing early on at boot.

This series fixes the regression by avoiding the use of deferred probing
when optimizing fw_devlink parsing.

Saravana Kannan (3):
  driver core: Don't do deferred probe in parallel with kernel_init
    thread
  driver core: Rename dev_links_info.defer_sync to defer_hook
  driver core: Avoid deferred probe due to fw_devlink_pause/resume()
