commit d322f6a24ee5964a58294f61bf96a1b6404c676d upstream.
A few patches slightly improving the output generated by decode_stacktrace.sh.
This patch (of 3):
Lines having a symbol to decode might not always have info after this symbol. It means ${info_str} might not be set, but it will always be printed after a space, causing trailing whitespaces.
That's a detail, but when the output is opened with an editor marking these trailing whitespaces, that's a bit disturbing. It is easy to remove them by printing this variable with a space only if it is set.
While at it, do the same with ${module} and print everything in one line.
