From 17a298e9ac7c011e64a9c0b6f807b43f9af22eac Mon Sep 17 00:00:00 2001 From: Mikko Perttunen Date: Thu, 10 Jun 2021 14:04:44 +0300 Subject: [PATCH] gpu: host1x: Add job release callback Add a callback field to the job structure, to be called just before the job is to be freed. This allows the job's submitter to clean up any of its own state, like decrement runtime PM refcounts.
