Subject: [PATCH 0/2] firewire: core: add device quirk detection

Hi,

In the history of this subsystem, we have experienced some device-specific
quirks. For example:

* afa1282a35d3 ("firewire: core: check for 1394a compliant IRM, fix inaccessibility of Sony camcorder").
* a509e43ff338 ("firewire: core: fix unstable I/O with Canon camcorder").
* 3a93d082bacf ("ALSA: firewire-motu: add support for MOTU Audio Express")

However, there is no common mechanism to handle such quirks. This patchset
adds a consistent approach for detecting and managing device-specific
quirks within the subsystem.

  firewire: core: detect device quirk when reading configuration ROM
  firewire: core: handle device quirk of MOTu Audio Express
