- 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. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (GNU/Linux) iQIcBAABAgAGBQJPa5I1AAoJEHnzb7JUXXnQvUoQAMl9PhUk5ZFhWp0AOnQ4uLhI lEfRnUp94kGBdazBhxM9wtAwZRAeXUev/JyxwymMKSG40dMTbuxqRcs71v6a+ifd VqNctL0yUncrOw/92l+TG2t/hWttB4u+dTKYX2U5yza42+uUHWMZb7MzmV+qVYc8 H+NR71WLQM4wkWdX8LBxmdeAOm0X635cjKsC/5FX9dws7q1ebSoxs4q4iIaGR7W8 ETWx5lh/UVyR7c9T+VIr0jfQWdsm2IcmHr/+nldlesePZ1gRjIEi69ErEnGxTkGe NLPwt9lWuFXgWWHBON7C/rLmBA+NSys9lbvRAsPXrb3GpOKlde81c7U7Kr/kmEkh hB9oM2Qh0A/7sglvIZiDUP565lqOAbXSJzziG3+0XgOP2zsxukm5gSecF8qM8tHY IDwN05R9+nc26NA5TOfaRWx08n9SqTxq4V326oz9WMuK4bosCEfg4dvMwyMK/V3i AyipAl2YYIG/2JURMFcGSKbw33dBw3mRsS8XG3MXwzagUMw/8tSyZKQIwF9qO4si 69QV7+CJoEfbJiLJMZJnKrRjfU+ZVRNA/xFuHUmhpmvYIbN8iJVGpGZABfXBUcH0 c1+qX9zE4NEAUEylbgn5raYSY6otF51O8QJzQOn2HRddBQSDpEwhkOGVfZ7zcSLH sjAOn9qLIMHnrxUXxBDP =oWbr -----END PGP SIGNATURE----- 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.
