5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: "Matthieu Baerts (NGI0)" matttbe@kernel.org
This reverts commit dc52117cd797f71f9686fa0cec91509eb7a9623d which is commit 2f3f53d62307262f0086804ea7cea99b0e085450 upstream.
In this kernel version, C89 is still the default ISO standard.
The reverted commit was fixing commit e8c07082a810 ("Kbuild: move to -std=gnu11"), introduced in v5.18, and not backported to older versions. It was then not supported to be backported to v5.15. It can then safely be reverted.
