Hi Christophe,

First bad commit (maybe != root cause):

tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 54917c90c2cfc6cf3be6deb143cf3967b6dd8d3b
commit: 2255411d1d0f0661d1e5acd5f6edf4e6652a345a powerpc/44x: Fix build failure with GCC 12 (unrecognized opcode: `wrteei')

I really can't see the link between that commit and the reported new
sparse errors.

Hi Christophe,

Sorry for the inconvience, the bot is stupid, it can't identify the fix
commit, obviously the commit here fixed the build error and exposed the
below warnings.

Best Regards,
Rong Chen
