[PATCH v2 0/3] MR2130: Fix missing *out=NULL in (WMReader|unknown_inner)_QueryInterface

[Ivan Chikish (＠nekotekina)]

QueryInterface should set *out to NULL on failure, as it seems to do in many different places.

This seems to be a regression from !888.
One old game started to crash on startup with this merge request.
I bisected it and it pointed to the commit 131ada052a2dbec66df695ce536ca048a2bd9174.

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:
