genirq/affinity: Remove const qualifier from node_to_cpumask argument
When CONFIG_CPUMASK_OFFSTACK isn't enabled, 'cpumask_var_t' is as 'typedef struct cpumask cpumask_var_t[1]', so the argument 'node_to_cpumask' alloc_nodes_vectors() can't be declared as 'const cpumask_var_t *' Fixes the following warning: kernel/irq/affinity.c: In function '__irq_build_affinity_masks': alloc_nodes_vectors(numvecs, node_to_cpumask, cpu_mask, ^ kernel/irq/affinity.c:128:13: note: expected 'const struct cpumask (*)[1]' but argument is of type 'struct cpumask (*)[1]' static void alloc_nodes_vectors(unsigned int numvecs, ^ Fixes: b1a5a73e64e9 ("genirq/affinity: Spread vectors on node according to nr_cpu ratio") Reported-by: kbuild test robot <lkp@intel.com> Signed-off-by: Ming Lei <ming.lei@redhat.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Link: https://lkml.kernel.org/r/20190828085815.19931-1-ming.lei@redhat.com
