[kbuild-all] arch/sh/kernel/cpu/sh2a/setup-sh7201.c:414:9: sparse: sparse: incorrect type in argument 1 (different base types)

Hi Luc, First bad commit (maybe != root cause): tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master head: 0da0a8a0a0e1845f495431c3d8d733d2bbf9e9e5 commit: e5fc436f06eef54ef512ea55a9db8eb9f2e76959 sparse: use static inline for __chk_{user,io}_ptr() date: 5 months ago config: sh-randconfig-s031-20210118 (attached as .config) compiler: sh4-linux-gcc (GCC)
