[PATCH 0/2] ALSA: oxfw: implement retries for scs1x at transaction failure
http://mailman.alsa-project.org/pipermail/alsa-devel/2016-February/104579.html
In thread of the post, I got some comments about work to extend ALSA
rawmidi core. I've investigated it in a few days ago and realized that it
may not so light work, mainly because of a lack of unified state
management[0].
In this development cycle, I'd like to give it up and use my time for the
other work within my plan for the cycle. Please just apply these two patches.
[0] In short, the state management is understandable for developers who
can understand it, and I'm not.

ALSA: oxfw: retry MIDI transferring for scs1x at transaction failure
ALSA: oxfw: discontinue MIDI substream for scs1x at transaction
failure
Applied both now. Thanks.
Thanks.
ALSA rawmidi core handles substreams for both directions, therefore
state management may not so simple as we expected (at least, for driver
based on packet streaming such as IEC 61883-1/6, there're more items to
be considered. So as USB MIDI Device class, too, I think). I'd like to
schedule the work to next developing cycle for Linux 4.7 or later.
