Simon Glass 96434a76fd env: Allow returning errors from hdelete_r() ... At present this function returns 1 on success and 0 on failure. But in the latter case it provides no indication of what went wrong. If an attempt is made to delete a non-existent variable, the caller may want to ignore this error. This happens when setting a non-existent variable to "", for example. Update the function to return 0 on success and a useful error code on failure. Add a function comment too. Make sure that env_set() does not return an error if it is deleting a variable that doesn't exist. We could update env_set() to return useful error numbers also, but that is beyond the scope of this change. Signed-off-by: Simon Glass <sjg@chromium.org> wip		2020-12-04 16:09:06 -05:00
