staging: rtl8188eu: 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
