Merge tag 'powerpc-5.19-6' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc fixes from Michael Ellerman:
- Re-enable the new amdgpu display engine for powerpc, as long as the
compiler is correctly configured.
- Disable stack variable initialisation in prom_init to fix GCC 12
allmodconfig.
Thanks to Dan Horák and Sudip Mukherjee.
