Multiple devices need S/R hooks (framebuffer, GPIO, camera). Add infrastructure and convert existing framebuffer code to the new model. This patch should create no functional change. Based on earlier work by Jonathan Corbet. Signed-off-by: Daniel Drake <dsd@laptop.org> Acked-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
