[PATCH V2 08/19] irqchip: crossbar: fix checkpatch warning

[Sricharan R <r.sricharan@xxxxxx>]

From: Nishanth Menon <nm@xxxxxx>

remove un-necessary space in function pointer.

Fixes checkpatch warning:
WARNING: Unnecessary space before function pointer arguments
 #37: FILE: drivers/irqchip/irq-crossbar.c:37:
 +	void (*write) (int, int);

WARNING: Missing a blank line after declarations
+	int *register_offsets;
+	void (*write)(int, int);

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);
