Re: [PATCH 0/1] MR3974: winemac.drv: Ensure user-land callback can access app_icon results.

[Jacek Caban (＠jacek)]

We shouldn't need to pass result pointer from unixlib to PE. It was needed during the transition (when the driver couldn't assume that it's executed on Unix stack), but at this point it's just a leftover. We can just have the result on PE stack now and just pass it to `NtCallbackReturn` when returning from the callback.
