Apologies if this has been reported or fixed already, I searched the
mailing list but did not see anything.
This change as commit 7ade3ca9cdb5 ("drm/amd/pm: correct the usage for
'supported' member of smu_feature structure") causes the following
errors/stacktrace when booting on a Ryzen 3 4300G based system, which
prevents me from reaching GNOME.
