[PATCH] src/common/dpp_crypto.c : fix uninitialised variable

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The current code generates a warning when compiled by Clang, because
if we goto 'fail:', pasword_len  can be uninitialised when we pass it
in to bin_clear_free().

Note that the actual usage is safe, because bin_clear_free() ignores
the second argument if the first argument is NULL, but it still seems
worth cleaning up.
