staging: rtl8192e: Standardize test for NULL.
The test for NULL of the return variable of functions was changed from (ret == NULL) to !ret to match the standard. Coccinelle was used with semantic patch: @@ expression e; identifier id, f; statement S; @@ f(...) { <+... id = \(kmalloc\|devm_kzalloc\|kmalloc_array\|devm_ioremap \|usb_alloc_urb\|alloc_netdev\|dev_alloc_skb\) (...) ... when any when != id = e + if (!id) - if (\(NULL == id\|id == NULL\)) S ...+> } Signed-off-by: Elise Lennion <elise.lennion@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
