[PATCH 0/6] firewire: core: partition fw_card spinlock

Hi,

The current implementation uses the fw_card spinlock for a wide range of
purposes, which goes against the theory that the type of lock should
protect critical sections as narrowly as possible.

This patchset adds some spinlocks for specific purposes, therefore
partitioning the existing wide-purpose lock.

Takashi Sakamoto (6):
  firewire: core: use scoped_guard() to manage critical section to
    update topology
  firewire: core: maintain phy packet receivers locally in cdev layer
  firewire: core: use spin lock specific to topology map
  firewire: core: use spin lock specific to transaction
  firewire: core: use spin lock specific to timer for split transaction
  firewire: core: annotate fw_destroy_nodes with must-hold-lock
