Subject[PATCH 4.9 40/61] include/asm-generic/topology.h: guard cpumask_of_node() macro argument
Date
From: Arnd Bergmann <arnd@arndb.de>

[ Upstream commit 4377748c7b5187c3342a60fa2ceb60c8a57a8488 ]

drivers/hwmon/amd_energy.c:195:15: error: invalid operands to binary expression ('void' and 'int')
(channel - data->nr_cpus));
~~~~~~~~~^~~~~~~~~~~~~~~~~
include/asm-generic/topology.h:51:42: note: expanded from macro 'cpumask_of_node'
#define cpumask_of_node(node) ((void)node, cpu_online_mask)
^~~~
include/linux/cpumask.h:618:72: note: expanded from macro 'cpumask_first_and'
#define cpumask_first_and(src1p, src2p) cpumask_next_and(-1, (src1p), (src2p))
^~~~~

Fixes: f0b848ce6fe9 ("cpumask: Introduce cpumask_of_{node,pcibus} to replace {node,pcibus}_to_cpumask")
Fixes: 8abee9566b7e ("hwmon: Add amd_energy driver to report energy counters")
