From: Nishanth Menon <nm@xxxxxx>
There is absolutely no need for crossbar driver to expose functions and
variables into global namespace. So make them all static
Also fix a couple of checkpatch warnings.
Fixes sparse warnings:
drivers/irqchip/irq-crossbar.c:129:29: warning: symbol 'routable_irq_domain_ops' was not declared. Should it be static?
drivers/irqchip/irq-crossbar.c:261:12: warning: symbol 'irqcrossbar_init' was not declared. Should it be static?
Checkpatch warnings:
WARNING: Prefer kcalloc over kzalloc with multiply
+ cb->irq_map = kzalloc(max * sizeof(int), GFP_KERNEL);
WARNING: Prefer kcalloc over kzalloc with multiply
+ cb->register_offsets = kzalloc(max * sizeof(int), GFP_KERNEL);
