Commit c045ceb5a145 ("reset: tegra-bpmp: Handle errors in BPMP
response") fixed an issue in the Tegra BPMP error handling but has
exposed an issue in the Tegra194 HDA driver and now resetting the
Tegra194 HDA controller is failing. For now revert the commit
c045ceb5a145 ("reset: tegra-bpmp: Handle errors in BPMP response")
while a fix for the Tegra HDA driver is created.

Is there some reason the subject and commit message does not follow 
normal revert convention (as done by 'git revert')?

Some maintainers prefer that the patch is not titled "Revert ..." and 
want the patch subject to follow the normal sub-system prefix. If you 
search through the patches for 'revert' in the subject you will see a 
mixture. I prefer this approach.

I see this has not been picked up yet for v5.16 and so I just wanted to 
check that you are planning to submit for v5.16.

Thanks!
