From 4dbf45e3c2f3acfd2096cb6a731d159492ddca99 Mon Sep 17 00:00:00 2001 From: Nishanth Menon Date: Thu, 26 Jun 2014 12:40:25 +0530 Subject: [PATCH] irqchip: crossbar: Fix sparse and checkpatch warnings 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); Signed-off-by: Nishanth Menon Signed-off-by: Sricharan R Acked-by: Santosh Shilimkar Link: https://lkml.kernel.org/r/1403766634-18543-8-git-send-email-r.sricharan@ti.com Signed-off-by: Jason Cooper --- drivers/irqchip/irq-crossbar.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/drivers/irqchip/irq-crossbar.c b/drivers/irqchip/irq-crossbar.c index 88fbe0f..f7eda9f 100644 --- a/drivers/irqchip/irq-crossbar.c +++ b/drivers/irqchip/irq-crossbar.c @@ -15,6 +15,7 @@ #include #include #include +#include #define IRQ_FREE -1 #define IRQ_RESERVED -2 @@ -118,7 +119,7 @@ found: return 0; } -const struct irq_domain_ops routable_irq_domain_ops = { +static const struct irq_domain_ops routable_irq_domain_ops = { .map = crossbar_domain_map, .unmap = crossbar_domain_unmap, .xlate = crossbar_domain_xlate @@ -139,7 +140,7 @@ static int __init crossbar_of_init(struct device_node *node) goto err1; of_property_read_u32(node, "ti,max-irqs", &max); - cb->irq_map = kzalloc(max * sizeof(int), GFP_KERNEL); + cb->irq_map = kcalloc(max, sizeof(int), GFP_KERNEL); if (!cb->irq_map) goto err2; @@ -184,7 +185,7 @@ static int __init crossbar_of_init(struct device_node *node) } - cb->register_offsets = kzalloc(max * sizeof(int), GFP_KERNEL); + cb->register_offsets = kcalloc(max, sizeof(int), GFP_KERNEL); if (!cb->register_offsets) goto err3; -- 2.7.4
