I already said it previously, I'm against an unconditional reset in a timeout
path. Make it a quirk or whatever, but in the current status, I'm against.

The previous behavior looks correct to me : upon timeout, retry, no need to
reset.

We still do return RETRY here, but also assert reset to I2C.

Anyway, lets revisit this again later. I will remove it in my next
version.

Thanks,
Vaibhav
