+Subject: [PATCH] main.c: revert check on console device
+
+Fix kernel panic because of the missing /dev/console.
+
+Revert Yocto-specific : "check console device file on fs when booting".
+
+The initramfs used in this kernel needs to be of the smallest possible
+size so we save a few kb by deploying an empty /dev which is populated
+after boot by the init (kexecboot checks and recreates the devices
+with or without devtmpfs).
