Todd Kjos 551a785c26 binder: fix handling of error during copy ... [ Upstream commit fe6b1869243f23a485a106c214bcfdc7aa0ed593 ] If a memory copy function fails to copy the whole buffer, a positive integar with the remaining bytes is returned. In binder_translate_fd_array() this can result in an fd being skipped due to the failed copy, but the loop continues processing fds since the early return condition expects a negative integer on error. Fix by returning "ret > 0 ? -EINVAL : ret" to handle this case.
