You are right, with commit 2bca25eaeba61 (Merge tag 'spi-v6.1' of 
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi) I am unable 
to reproduce it.

In 5.15.71 we have:

     [    1.357209] ACPI: Core revision 20210730

while in Linus’ current master (“6.1-rc0”) we have:

     [    1.377877] ACPI: Core revision 20220331


Kind regards,

Paul
