Rafał Miłecki e1491b341b kernel: mtdsplit: modify rootfs helpers to provide partition type
Our mtdsplit parsers may want to create partition with name choice based
on partition file system (e.g. SquashFS vs. JFFS2). This patch allows
passing extra argument pointing to variable that will be set properly.
