[PATCH] powerpc: Minor numa memory code cleanup
I started to add missing of_node_put() calls to the routines that determine the number of cells for memory. Decided to combine the routines instead of making separate node lookups. Changed variable names to help with some confusion as to meaning. Signed-off-by: Mike Kravetz <kravetz@us.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
