Merge 6.17-rc6 into kbuild-next
Commit bd7c2312128e ("pinctrl: meson: Fix typo in device table macro")
is needed in kbuild-next to avoid a build error with a future change.
While at it, address the conflict between commit 41f9049cff32 ("riscv:
Only allow LTO with CMODEL_MEDANY") and commit 6578a1ff6aa4 ("riscv:
Remove version check for LTO_CLANG selects"), as reported by Stephen
Rothwell [1].
