NAK
saved_ec is allocated if flag EC_FLAGS_VALIDATE_ECDT is true.
EC_FLAGS_SKIP_DSDT_SCAN have no sense in such case, thus this new code path
is never executed.
On the other hand, unconditionally freeing pointer, which is might be NULL, is not
right either.
So, this patch introduced more problems as it tries to solve...

Alex.
