-       that there is no unexpected or expected token to report.  In that
-       case, just report a simple "syntax error".
-     - Don't assume there isn't a lookahead just because this state is a
-       consistent state with a default action.  There might have been a
-       previous inconsistent state, consistent state with a non-default
-       action, or user semantic action that manipulated yychar.
-     - Of course, the expected token list depends on states to have
-       correct lookahead information, and it depends on the parser not
-       to perform extra reductions after fetching a lookahead from the
-       scanner and before detecting a syntax error.  Thus, state merging
-       (from LALR or IELR) and default reductions corrupt the expected
-       token list.  However, the list is correct for canonical LR with
-       one exception: it will still contain any token that will not be
-       accepted due to an error action in a later state.

-# Simple script to update the version of DTC carried by the Linux kernel
-#
-# This script assumes that the dtc and the linux git trees are in the
-# same directory. After building dtc in the dtc directory, it copies the
-# source files and generated source files into the scripts/dtc directory
-# in the kernel and creates a git commit updating them to the new
-# version.
-#
-# Usage: from the top level Linux source tree, run:
-# $ ./scripts/dtc/update-dtc-source.sh
-#
-# The script will change into the dtc tree, build and test dtc, copy the
-# relevant files into the kernel tree and create a git commit. The commit
-# message will need to be modified to reflect the version of DTC being
-# imported
-#
-# TODO:
-# This script is pretty basic, but it is seldom used so a few manual tasks
-# aren't a big deal. If anyone is interested in making it more robust, the
-# the following would be nice:
-# * Actually fail to complete if any testcase fails.
-#   - The dtc "make check" target needs to return a failure
-# * Extract the version number from the dtc repo for the commit message
-# * Build dtc in the kernel tree
-# * run 'make check" on dtc built from the kernel tree
