Hi,

Between core and 1394 ohci driver modules, the data of 'struct
fw_packet' is utilized to deliver data of asynchronous packet.
Especially, its 'header' array member is for the parameters of packet.
However, the serialization/deserialization are done by local hard-coded
macro in each module. It is inconvenient.

This series of changes adds some inline helper functions to replace
them. A KUnit test is also added to check them.

Takashi Sakamoto (8):
  firewire: core: add common inline functions to serialize/deserialize
    asynchronous packet header
  firewire: core: replace local macros with common inline functions for
    asynchronous packet header
  firewire: ohci: replace local macros with common inline functions for
    asynchronous packet header
  firewire: ohci: replace hard-coded values with inline functions for
    asynchronous packet header
  firewire: ohci: replace hard-coded values with common macros
  firewire: core: obsolete tcode check macros with inline functions
  firewire: core: add common macro to serialize/deserialize isochronous
    packet header
  firewire: core: replace local macros with common inline functions for
    isochronous packet header
