From e074d08e2b98db1b19328bb9395052b34366831d Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Wed, 18 Apr 2012 22:16:47 +0000 Subject: [PATCH] powerpc/windfarm: const'ify and add "priv" field to controls & sensors const'ify the sensor ops and name and add a void* for use by the control and sensor drivers to point back to their private data, avoiding the need to create a wrapper data structure per sensor or control instance.
