[PATCH v2 3/7] fixdep: factor out common code for reading files

Now, do_config_files() and print_deps() are almost the same. Only the difference is the parser function called (parse_config_file vs parse_dep_file). We can reduce the code duplication by factoring out the common code into read_file() - this function allocates a buffer and loads a file to it.

[PATCH v2 6/7] fixdep: refactor parse_dep_file()

parse_dep_file() has too much indentation, and puts the code far to the right. This commit refactors the code and reduces the one level of indentation. strrcmp() computes 'slen' by itself, but the caller already knows the length of the token, so 'slen' can be passed via function argument. With
