Merge tag 'firewire-updates' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394
Pull IEEE 1394 (FireWire) subsystem updates post v3.3 from Stefan Richter: - Some SBP-2 initiator fixes, side product from ongoing work on a target. - Reintroduction of an isochronous I/O feature of the older ieee1394 driver stack (flush buffer completions); it was evidently rarely used but not actually unused. Matching libraw1394 code is already available. - Be sure to prefix all kernel log messages with device name or card name, and other logging related cleanups. - Misc other small cleanups, among them a small API change that affects sound/firewire/ too. Clemens Ladisch is aware of it. * tag 'firewire-updates' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394: (26 commits) firewire: allow explicit flushing of iso packet completions firewire: prevent dropping of completed iso packet header data firewire: ohci: factor out iso completion flushing code firewire: ohci: simplify iso header pointer arithmetic firewire: ohci: optimize control bit checks firewire: ohci: remove unused excess_bytes field firewire: ohci: copy_iso_headers(): make comment match the code firewire: cdev: fix IR multichannel event documentation firewire: ohci: fix too-early completion of IR multichannel buffers firewire: ohci: move runtime debug facility out of #ifdef firewire: tone down some diagnostic log messages firewire: sbp2: replace a GFP_ATOMIC allocation firewire: sbp2: Fix SCSI sense data mangling firewire: sbp2: Ignore SBP-2 targets on the local node firewire: sbp2: Take into account Unit_Unique_ID firewire: nosy: Use the macro DMA_BIT_MASK(). firewire: core: convert AR-req handler lock from _irqsave to _bh firewire: core: fix race at address_handler unregistration firewire: core: remove obsolete comment firewire: core: prefix log messages with card name ...
