staging: rtl8188eu: core: Use put_unaligned_le16
Introduce the use of function put_unaligned_le16.
This is done using the following Coccinelle semantic patch:
//<smpl>
@@ identifier tmp; expression ptr; expression y,e; type T; @@
- tmp = cpu_to_le16(y);
<+... when != tmp
- memcpy(ptr, (T)&tmp, ...);
+ put_unaligned_le16(y,ptr);
...+>
? tmp = e
@@ type T; identifier tmp; @@
- T tmp;
...when != tmp
//</smpl>
Corresponding header file has been added too.
