Hi,
This patchset is a revised version of my previous one: [alsa-devel] [PATCH 0/8] ALSA: firewire-lib/firewire-tascam: localize async midi port http://mailman.alsa-project.org/pipermail/alsa-devel/2017-April/119748.html
A bug of this feature was reported: http://mailman.alsa-project.org/pipermail/alsa-devel/2017-April/119775.html
And I posted a fix: http://mailman.alsa-project.org/pipermail/alsa-devel/2017-April/119782.html
The fix brought conflict to the previous patchset and this is a revised version.
