Note a set of changes for the qcom adc driver rely on an immutable

That part is fine, but what _isn't_ great is the merge commit message.

This is the message in its entirety:

   "Merge remote-tracking branch
'iio-thermal-5.11-rc1/ib-iio-thermal-5.11-rc1' into testing"

Notice how it doesn't say _anything_ useful.

Merges are commits, and they should have commit messages with
*explanation* the same way all regular commits should. In fact, they
generally should have *more* explanation, since they are fundamentally
more interesting and subtle than some one-liner obvious bug-fix.

So this all looks otherwise fine, and I like how you were clearly
aware of the whole cross-tree merge, and how you let me kn0ow about
it. I appreciate that part, and I've pulled your branch.

But I wanted to really take this moment to point out that merge
commits really should have messages explaining *why* and *what* got
merged. Not just the technical "I merged that tree".
