[ Upstream commit 8c576f87ad7eb639b8bd4472a9bb830e0696dda5 ] In order to later move this variable within the opaque structure, let's create a helper for accessing it in read-only mode. This helper will be exposed to device drivers and kept accessible for the few that could need it. The write access to this variable however should be fully reserved to the core so in a second step we will hide this variable into the opaque structure.
