makedevs: don't restrict device node paths to 40 characters
40 character paths work OK for device nodes in /dev but not for device nodes created in a chroot, LXC container, etc. Since the 'path' array is already a 4k buffer, the sscanf 40 character limit seems to be a typo or historical mis-merge. Update the sscanf limit and bring the code in sync with the Buildroot version: https://git.buildroot.net/buildroot/commit/?id=8876b6751e0bc19a3754290061808f0f8420708e Signed-off-by: Andre McCurdy <armccurdy@gmail.com> Signed-off-by: Ross Burton <ross.burton@intel.com>
