Subject: [PATCH] genirq/affinity: Remove const qualifier from node_to_cpumask

 argument

References: bsc#1174897 ltc#187090

Patch-mainline: v5.4-rc1

Git-commit: 101f85b56d03b36418bbf867f67d81710839b0ec

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")
