Hello! I hit into a compilation error while making a build for ath79 It apparently seems to have a trivial fix but I cannot say for sure with superficial investigation. Adding into CC: the author and reviewer of the commit that appears to be the root cause. You might have a better understanding of the causes and consequences. Root cause: commit b83ba0b9df56 ("MIPS: of: Introduce helper function to get DTB") When reproducing the error my diff of the default ath79_defconfig is: -# CONFIG_RD_GZIP is not set +CONFIG_INITRAMFS_SOURCE="initramfs.txt" -CONFIG_MIPS_CMDLINE_FROM_DTB=y +CONFIG_PRINTK_TIME=y -CONFIG_CMDLINE="rootfstype=squashfs,jffs2" +CONFIG_CMDLINE="console=ttyS0,115200 rootfstype=ramfs" +CONFIG_CMDLINE_OVERRIDE=y Cheers, Mauri Mauri Sandberg (1): MIPS: kernel: setup.c: fix compilation error arch/mips/kernel/setup.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) base-commit: 509d36a941a3466b78d4377913623d210b162458 -- 2.25.1
