Thanks. It's important that ath11k is taken into account while making
changes to MHI, otherwise there can easily be regressions.
I was looking at commit ed39d7816885 ("bus: mhi: Remove auto-start
option") and noticed this in the commit log:
This is really up to the MHI device(channel) driver to manage the state
of its channels.
So does this mean we have to make changes in ath11k to accomodate this?
I haven't tested linux-next yet.
