Subject: [PATCH 0/2] staging: vchiq_arm: Fix drv_mgmt leak
Date: Sun, 13 Oct 2024 14:15:27 +0530 [thread overview]
Message-ID: <20241013084529.377488-1-umang.jain@ideasonboard.com> (raw)
1/2 is a drive by fix.
2/2 uses devres resouce management helper devm_kzalloc() to auto-free
struct vchiq_drv_mgmt on error and .remove() paths.
It might be good to aware the devres issue and following talk might
give reviewers a helpful context:
- https://lpc.events/event/16/contributions/1227/
- https://archive.fosdem.org/2023/schedule/event/devm_kzalloc/
I am not totally sure if these problems, causes a blockers for these
patches. There are a couple of memory management issues I've spotted
which can be fixed? by devres (similar to this series) but probably I
will wait for initial feedback on this series.
