Build failure is

A suggested fix is at https://lore.kernel.org/lkml/20220618232737.2036722-1-linux@roeck-us.net/ but drm maintainers don't seem to be happy with it. I am not aware of an alternate patch.
I still see the following runtime warning.
WARNING: CPU: 0 PID: 1 at lib/refcount.c:28 of_platform_bus_create+0x33c/0x3dc refcount_t: underflow; use-after-free.
for which a fix is available in -next (ARM: 9207/1: amba: fix refcount underflow if amba_device_add() fails).
Also, there is
WARNING: CPU: 0 PID: 1 at kernel/smp.c:905 smp_call_function_many_cond+0x280/0x544
which is seen on some arm platforms if KFENCE is enabled. This is not a new problem. I'll probably disable KFENCE on affected platforms to reduce the noise.
