David, please take this into net-next as soon as possible.  When the
IPA code was merged the other day this prerequisite patch was not
included, and as a result the IPA driver fails to build.  Thank you.

In particular, this seems to now have regressed into mainline for the 5.7
merge window as reported by Linaro's ToolChain Working Group's CI.

Is the problem you're referring to the result of a build done
in the midst of a bisect?

The fix for this build error is currently present in the
torvalds/linux.git master branch:
    6fcd42242ebc soc: qcom: ipa: kill IPA_RX_BUFFER_ORDER

I may be mistaken, but I believe this is the same problem I discussed
with Maxim Kuvyrkov this morning.  A different build problem led to
an automated bisect, which conluded this was the cause because it
landed somewhere between the initial pull of the IPA code and the fix
I reference above.
