[PATCH 0/5] firewire: ohci: refactor local AT request/response handling

[Takashi Sakamoto]

This series refactors the handling of asynchronous transactions to the local
node in the OHCI driver.

The current implementation has several special cases for transactions to
the two CSR address ranges on the local node. The code for detecting these
cases and generating the corresponding response packets is spread across
conditional and switch statements, making the handling difficult to follow.

This series first factors out the detection of the CSR address ranges and
local AT request/response packets. It then simplifies the response handling
and separates the request and response paths into different helper functions.

No functional changes are intended.


Takashi Sakamoto (5):
  firewire: ohci: use in_range() macro to detect CSR address ranges
  firewire: ohci: add helper function to detect local AT
    request/response packets
  firewire: ohci: refactor multiple calls to fw_fill_response()
  firewire: ohci: refactor local response packet handling
  firewire: ohci: refactor handling of local AT request/response packets
