Changes to the FireWire kernel drivers in Linux 3.3

[Stefan R. <st...@s5...>]

Hi all,

Linux 3.3 has been released on Sunday.  This time there were only two
small changes to the FireWire drivers.

firewire-ohci:
  - Add workaround for the 1394 part of Creative SoundBlaster Audigy
    in order to fix transaction failures.
  - Fix random malfunctions of Ricoh PCI Express 1394 controllers by
    disabling MSI (message signaled interrupts).

These changes were also backmerged into kernel 3.2.6 and 3.0.21.  In
kernel 3.0.25, two forgotten older fixes from the 3.1 release were
backmerged (fix for recognition of some old camcorders; 32 bit userspace on
64 bit kernel compatibility fix).

Loosely related to FireWire (but also USB, SATA, and other interconnects):
Just last week between 3.3-rc7 and 3.3 final, some fixes for kernel
crashes at hot unplug of storage devices were committed.  E.g. an infamous
bug with card readers has been addressed.  Nevertheless I suspect that the
hunt for hot-unplug related bugs in and around the kernel's block layer is
not yet over.

Since there is so little to say about the FireWire kernel drivers, I use
this post to also remind of some library updates:
  - libraw1394 v2.0.8 on 2012-02-19 with bug fixes and performance
    improvement,
  - libdc1394 v2.2.0 on 2012-03-06 with bug fixes on Linux and with new
    Windows platform support,
  - ongoing libffado fixes and improvements in the FFADO development
    repository, without formal release yet.
