[kbuild-all] [zen-kernel-zen-kernel:5.6/exfat 12/15] fs/exfat/super.c:669:17: error: initialization from incompatible pointer type

Hi Namjae, First bad commit (maybe != root cause): tree: https://github.com/zen-kernel/zen-kernel 5.6/exfat head: 669f683801d1ef2a6716baa6363ef33379be6da5 commit: 42256ca2e038dc7fd23e4c19898877392bd3d512 [12/15] exfat: add exfat in fs/Kconfig and fs/Makefile config: i386-allyesconfig (attached as .config) compiler: gcc-7 (Debian 7.4.0-6) 7.4.0 reproduce: git checkout 42256ca2e038dc7fd23e4c19898877392bd3d512 # save the attached .config to linux build tree make ARCH=i386 If you fix the issue, kindly add following tag Reported-by: kbuild test robot <lkp(a)intel.com&gt; Note: the zen-kernel-zen-kernel/5.6/exfat HEAD 669f683801d1ef2a6716baa6363ef33379be6da5 builds fine. It only hurts bisectibility.
