For example, libdc1394 was affected. - more consistent retry stategy in device discovery/ rediscovery, and improved failure diagnostics - various small cleanups, e.g. use SCSI layer's DMA mapping API in firewire-sbp2 * tag 'firewire-updates' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394: firewire: sbp2: document the absence of alignment requirements firewire: sbp2: remove superfluous blk_queue_max_segment_size() call firewire: sbp2: use scsi_dma_(un)map firewire: sbp2: give correct DMA device to scsi framework firewire: core: fw_device_refresh(): clean up error handling firewire: core: log config rom reading errors firewire: core: log error in case of failed bus manager lock firewire: move rcode_string() to core firewire: core: improve reread_config_rom() interface firewire: core: wait for inaccessible devices after bus reset firewire: ohci: omit spinlock IRQ flags where possible firewire: ohci: correct signedness of a local variable firewire: core: fix DMA mapping direction firewire: use module_pci_driver 2012-05-14T08:43:43Z Clemens Ladisch clemens@ladisch.de 2012-05-13T17:07:22Z urn:sha1:92b862c7d685f5971a954e6ded51891d4adc412b Trying to flush completed packets is pointless when the pointer callback was called from the packet completion callback; avoid it.

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.

Likewise, let firewire-core maintain an fw_device reference for the entire lifetime of an fw_unit so that fw_unit drivers don't have to.
