Merge tag 'powerpc-6.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc fixes from Michael Ellerman: - Finish a refactor of pgprot_framebuffer() which dependend on some changes that were merged via the drm tree - Fix some kernel-doc warnings to quieten the bots Thanks to Nathan Lynch and Thomas Zimmermann. * tag 'powerpc-6.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: powerpc/rtas: Fix ppc_rtas_rmo_buf_show() kernel-doc powerpc/pseries/rtas-work-area: Fix rtas_work_area_reserve_arena() kernel-doc powerpc/fb: Call internal __phys_mem_access_prot() in fbdev code powerpc: Remove file parameter from phys_mem_access_prot() powerpc/machdep: Remove trailing whitespaces
