Staging: speakup: Remove print following unsuccessful kmalloc
Remove print statement following unsuccessful kmalloc when there is not enough memory. Kmalloc and variants normally produce a backtrace in such a case. Hence, a print statement is not necessary. Found using the following Coccinelle semantic patch: @@ identifier i; @@ i = (\(kmalloc\|devm_kzalloc\|kmalloc_array\| devm_ioremap\|usb_alloc_urb\|alloc_netdev\|dev_alloc_skb\| kzalloc\|kcalloc\|kmem_cache_alloc\|kmem_cache_zalloc\| kmem_cache_alloc_node\|kmalloc_node\|kzalloc_node\)(...)); ( if (i == NULL) { -\(DBG_8723A\|printk\|pr_err\|CERROR\|DBG_88E\)(...); ...when any } | if (!i) { -\(DBG_8723A\|printk\|pr_err\|CERROR\|DBG_88E\)(...); ...when any } ) @@ identifier i; @@ ( - if (i == NULL) { + if (i == NULL) return ...; - } | - if (!i) { + if (!i) return ...; - } ) Signed-off-by: Meghana Madhyastha <meghana.madhyastha@gmail.com> Acked-by: Julia Lawall <julia.lawall@lip6.fr> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
