[PATCH V4 07/16] irqchip: crossbar: Fix sparse and checkpatch warnings

From: Sricharan R
Date: Thu Jun 26 2014 - 03:16:11 EST


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);
