Gabriel Ivăncescu : mshtml: Don't check for NULL outer_window from within HTMLWindow* methods.
Module: wine Branch: master Commit: 9bdfe8ee25e2574d8fefe591fe48784aba67d4f9 URL: https://gitlab.winehq.org/wine/wine/-/commit/9bdfe8ee25e2574d8fefe591fe48784... Author: Gabriel Ivăncescu <gabrielopcode(a)gmail.com> Date: Mon Dec 4 17:27:58 2023 +0200 mshtml: Don't check for NULL outer_window from within HTMLWindow* methods. These methods are not called from any of our objects that hold ref to the inner window only, and since we return outer windows to external callers now, they *must* have a ref to the outer window, which effectively means these cannot be NULL. And some other places didn't check for NULL either (e.g. get_parent).
