Subject: [PATCH 2/4] omap iommu: Add module information to struct iommu_functions
Date: Fri, 25 Mar 2011 17:18:00 +0200 [thread overview]
Message-ID: <1301066282-8040-2-git-send-email-sakari.ailus@maxwell.research.nokia.com> (raw)
In-Reply-To: <4D8CB217.1050909@maxwell.research.nokia.com>
Whichever module that implements the struct, may not be unloaded while it's
in use. Prepare to this by adding module reference to the structure.
