staging: greybus: hid: Remove print following unsuccessful kmalloc
Challenge suggested by Coccinelle 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,print; constant char [] c; @@ 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) { -print(...,c,...); ...when any } | if (!i) { -print(...,c,...); ...when any } ) Signed-off-by: Sanjana Sanikommu <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
