of: unify phandle name in struct device_node
In struct device_node, the phandle is named 'linux_phandle' for PowerPC and MicroBlaze, and 'node' for SPARC. There is no good reason for the difference, it is just an artifact of the code diverging over a couple of years. This patch renames both to simply .phandle. Note: the .node also existed in PowerPC/MicroBlaze, but the only user seems to be arch/powerpc/platforms/powermac/pfunc_core.c. It doesn't look like the assignment between .linux_phandle and .node is significantly different enough to warrant the separate code paths unless ibm,phandle properties actually appear in Apple device trees. I think it is safe to eliminate the old .node property and use phandle everywhere. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.
