From d3b814bb1e8b0c63449a3430196c20cbe24a3e67 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 19 Jun 2007 16:07:58 +1000 Subject: [PATCH] [POWERPC] Generalise device_node flag interface The struct device_node currently has a _flags variable, although it's only used for one flag - OF_DYNAMIC. Generalise the flag accessors so we can use them with other flags in future.
