Subject: [PATCH v2 6/6] drm/omap: gem: Switch to gem_free_object_unlocked()
Date: Fri, 25 May 2018 19:39:25 +0300	[thread overview]
Message-ID: <20180525163925.10736-7-laurent.pinchart@ideasonboard.com> (raw)
In-Reply-To: <20180525163925.10736-1-laurent.pinchart@ideasonboard.com>

From: Daniel Vetter <daniel.vetter@ffwll.ch>

The only thing that omap_gem_free_object does that might need the magic
protection of struct_mutex (of keeping all objects alive if that lock is
held, even if the last reference is gone) is the mm_list manipulation.
This is already protected by the separate omapdrm->list_lock, which
means that struct_mutex is not needed by omapdrm. We can switch to
gem_free_object_unlocked()
