checkkconfigsymbols.py: find similar symbols
Add support to find string-similar symbols. When option --sim SYM is specified, checkkconfigsymbols.py will print at most 10 symbols defined in Kconfig that are string similar to SYM in the following format: Similar symbols: $COMMA_SEPARATED_LIST_OF_SYMBOLS Note, if no similar symbols are found it is indicated as follows: Similar symbols: no similar symbols found Since the implemented functionality is also useful when searching the entire source or when diffing two commits, a list of similar symbols is printed unconditionally with the other data. In order to make the output more readable, the format now looks as follows: $UNDEFINED_SYMBOL Referencing files: $COMMA_SEPARATED_LIST_OF_FILES Similar symbols: $COMMA_SEPARATED_LIST_OF_SYMBOLS [Optional with '--find'] Commits changing symbol: - $COMMIT_1_HASH ("$COMMIT_1_MESSAGE") - $COMMIT_2_HASH ("$COMMIT_2_MESSAGE") or - no commit found Signed-off-by: Valentin Rothberg <valentinrothberg@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
