Thanks Nathan, (bit embarrassed I missed this in review :(
As you probably guessed I didn't run an llvm test this time - guess I should
start doing that on a regular basis.
We obviously have plenty of time to get this fix in place but
seeing as I just sent a pull request for the driver a few hours before this
patch:
Greg, would you mind picking this one up directly on top of
[PULL] 2nd set of IIO new device support, features, cleanup for 5.16
if you take that pull request?
Message ID for this one is:
[email protected]
No problem if you'd rather I just queue this fix up for post merge
window.

Thanks,
