Subject: [PATCH v2 0/2] firewire: core: revert "serialize topology building and bus manager work"

Hi,

The patchset that serialized bm_work() and fw_core_handle_bus_reset()
was merged without sufficient consideration of the race condition during
fw_card removal.

This patchset reverts some commits and restores the acquisition of the
fw_card spin lock.

Changes from v1:
* Fulfill cover-letter title

Takashi Sakamoto (2):
  Revert "firewire: core: shrink critical section of fw_card spinlock in
    bm_work"
  Revert "firewire: core: disable bus management work temporarily during
    updating topology"
