Hey Sriman,
Great work splitting up your original code. I'm afraid that I see some
of the patches as still needing more splitting up to be easily
reviewable, especially "HID: steelseries: Add async support and unify
device definitions".
The code looks good to me from a cursory glance, though we probably
want to get more eyeballs on the sound code.
I won't have time to test this patchset on real hardware for a little
while, but I'll test this version or any updates if there are any when
I have time.
I also don't know what out subsystem maintainers think, but, if you
have the patience, this might be the opportunity to split off the
headset support from the completely unrelated force feedback steering
wheel driver. I'm not going to block your patchset on this but
something to consider for the future.
Cheers
