[bitbake-devel] [PATCH 1/2] bb.data_smart: retain traceback from ExpansionError

[Christopher Larson]

From: Christopher Larson <chris_larson at mentor.com>

This gives us the needed context of the original ExpansionError, which is
invaluable when we have a chain of function calls in the expansion.
