From f2faea8b64125852fa9acc6771c07fc0311a039b Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Fri, 20 Aug 2021 22:18:30 +0200 Subject: [PATCH] drm/etnaviv: add missing MMU context put when reaping MMU mapping When we forcefully evict a mapping from the the address space and thus the MMU context, the MMU context is leaked, as the mapping no longer points to it, so it doesn't get freed when the GEM object is destroyed. Add the mssing context put to fix the leak.
