I understand, happened to me as well. Is it okay to CC you on patches?
Or are you too far away from it meanwhile?

Real HW setups for testing are a problem, yes. I noticed this, too, when
I said I fix the existing drivers. I reconsidered. Fixing them would
result in non-trivial changes which need testing SMBUS_BLOCK_DATA
transfers. This is too rare, so I'll just focus on the systems I have at
hand. Digging in deeper, I found there is enough to fix at the core
level anyhow. I won't be bored.

Yeah, I hope it grows the pool of interested people.

All the best,
