Backport Linux commit cdf315f907d4. This is the clean backport without
any changes.
When handling faults from the event or PRI queue, we need to find the
struct device associated with a SID. Add a rb_tree to keep track of
SIDs.

I think that by only backporting this one we are introducing a regression for
which
we don’t allow anymore duplicated stream id, have a look on this linux commit
that is fixing it: b00d24997a11c10d3e420614f0873b83ce358a34.
I will backport the logic from this commit also
P.s. I was able to apply only until patch 3, I think this serie needs a rebase,
do you have
an updated branch or can you point me to the staging SHA to build it? (hope
it’s not too far
from now)
Yes, sorry for that, it's conflicting with the couple of recently merged
commits, rebased for the new version.
Cheers,
Luca
Best regards,
Milan
