From 849fb0a8878336732165eb482d3f0e8a4f71dd03 Mon Sep 17 00:00:00 2001 From: James A Shackleford Date: Tue, 24 Jun 2014 22:52:38 -0400 Subject: [PATCH] staging: rtl8712: remove wrapper function get_next get_next is just an inline wrapper around return list->next. This patch removes the wrapper and directly uses list->next where applicable.
