Subject: [PATCH] staging: rtl8712: mlme_linux: Clean up tests if NULL returned
on failure
Some functions like 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
