Subject: [PATCH] list: Remove duplicated and unused macro
 list_for_each_reverse

From: Zijun Hu <quic_zijuhu@...cinc.com>

Remove macro list_for_each_reverse due to below reasons:

- it is same as list_for_each_prev.
- it is not used by current kernel tree.

Fixes: 8bf0cdfac7f8 ("<linux/list.h>: Introduce the list_for_each_reverse() method")
