[alsa-devel] emi62 (may be slightly off-topic)

[Monty Montgomery]

Karl just reminded me that I never sent a link to my up-to-date out of
tree eMagic driver update.  Here's the latest version:

http://people.xiph.org/~xiphmont/emagic/emi-20131209.tgz

This includes the latest/correct firmware for the 2|6 and 6|2m (not
the same as shipped in the kernel).  It builds a single emi.ko that
functions as a loader for both devices.
There's the usual make and make install target, as well as a
'remove-old' target that kills off the old installed firmware and
emi26/62 modules.

The Makefile is a bit slapdash, hopefully it doesn't misbehave.

I've mentioned it before, but the current in-kernel loader (and
official firmware) are both outright broken. I'm happy enough to
maintain this out of kernel (since there were objections to updating
the firmware), but the in-tree / mainline stuff should be either
updated or removed.  It simply doesn't work.
