Some functions like kmalloc/kzalloc return NULL on failure. When NULL represents failure, !x is commonly used. This was done using Coccinelle: @@ expression *e; identifier l1; @@ e = \(kmalloc\|kzalloc\|kcalloc\|devm_kzalloc\)(...); ... - e == NULL + !e Signed-off-by: simran singhal <singhalsimran0@xxxxxxxxx> --- drivers/staging/vc04_services/interface/vchiq_arm/vchiq_util.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/staging/vc04_services/interface/vchiq_arm/vchiq_util.c b/drivers/staging/vc04_services/interface/vchiq_arm/vchiq_util.c index e0ba0ed..7fa0310 100644 --- a/drivers/staging/vc04_services/interface/vchiq_arm/vchiq_util.c +++ b/drivers/staging/vc04_services/interface/vchiq_arm/vchiq_util.c @@ -52,7 +52,7 @@ int vchiu_queue_init(VCHIU_QUEUE_T *queue, int size) sema_init(&queue->push, 0); queue->storage = kzalloc(size * sizeof(VCHIQ_HEADER_T *), GFP_KERNEL); - if (queue->storage == NULL) { + if (!queue->storage) { vchiu_queue_delete(queue); return 0; } -- 2.7.4 _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
