Nikolay Sivov : mfreadwrite/reader: Allocate output samples on read requests.
Module: wine Branch: master Commit: 68fa3f673633c138596b86ad2ed1befcd0cc63c5 URL: https://source.winehq.org/git/wine.git/?a=commit;h=68fa3f673633c138596b86ad2... Author: Nikolay Sivov <nsivov(a)codeweavers.com> Date: Fri May 13 19:34:13 2022 +0300 mfreadwrite/reader: Allocate output samples on read requests. Instead of tracking when free notifications, simply propagate allocation error to the caller. Behavior spotted by Giovanni.
