staging: rtl8192e: Remove unnecessary code
kfree on NULL pointer is a no-op.
This used the following semantic patch to identify such a instance
// <smpl>
@@ expression E; @@
- if (E != NULL) { kfree(E); }
+ kfree(E);
@@ expression E; @@
- if (E != NULL) { kfree(E); E = NULL; }
+ kfree(E);
+ E = NULL;
// </smpl>
As rxb is always null at this point, so the code to kfree it and intializing
it to NULL is removed completely.
