[PATCH] RDS: Simplify code

From: Christophe JAILLET
Date: Sat Sep 03 2016 - 01:34:27 EST


Calling 'list_splice' followed by 'INIT_LIST_HEAD' is equivalent to
'list_splice_init'.

This has been spotted with the following coccinelle script:
/////
@@
expression y,z;
@@

- list_splice(y,z);
- INIT_LIST_HEAD(y);
+ list_splice_init(y,z);
