[regressions] ath11k: v5.12.3 mhi regression

Hi,

I got several reports that this mhi commit broke ath11k in v5.12.3:

commit 29b9829718c5e9bd68fc1c652f5e0ba9b9a64fed Author: Bhaumik Bhatt bbhatt@codeaurora.org Date: Wed Feb 24 15:23:04 2021 -0800

bus: mhi: core: Process execution environment changes serially

[ Upstream commit ef2126c4e2ea2b92f543fae00a2a0332e4573c48 ]

Here are the reports:

https://bugs.archlinux.org/task/70849?project=1&string=linux

Interestingly v5.13-rc1 seems to work fine, at least for me, though I have not tested v5.12.3 myself. Can someone revert this commit in the stable release so that people get their wifi working again, please?
