Subject: [PATCH] ieee1394: sbp2: add workarounds for 2nd and 3rd generation
iPods
as per https://bugs.launchpad.net/bugs/294391. These got one sample of
each iPod generation going. However there still occurred I/O stalls
with the 3rd generation iPod which remain undiagnosed at the time of
this writing.
