Thanks for the patches. But, as the 6.6 merge window open is pretty close, I'd postpone those unless it's urgently needed.
I have no timeline since we have the workaround in, hence the RFC
Also, before moving the resource tied with the device object, we'll need a refcount to the ctl dev from pcm dev, as PCM does release chmap at its free path (calling free_chmap()). Otherwise it'll lead to another UAF, if both objects releases are done asynchronously without dependency.
Got it, thanks.
BTW, the cover letter and the subject prefix of the patches don't match, and also the cover letter didn't include Cc. Please try to make both cover letter and patches sent properly.
Thanks for catching that, I was struggling getting cc to copy across with git from get_maintainers. I will give it another shot with v2.
