[RFC PATCH 3/7] kconfig: remove const qualifier from sym_expand_string_value()

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

 



This function returns realloc'ed memory, so the returned pointer
must be passed to free() when done.  Change the return value type
to save casting.
