From 763506a37899ac24357dd474d102130b0e01a8bb Mon Sep 17 00:00:00 2001
From: Jack Zhang <Jack.Zhang1@amd.com>
Date: Tue, 3 Sep 2019 10:15:23 +0800
Subject: [PATCH 3676/4256] drm/amd/amdgpu: add sw_fini interface for df_funcs
add sw_fini interface of df_funcs.
This interface will remove sysfs file of df_cntr_avail
function.
The old behavior only create sysfs of df_cntr_avail
in sw_init, but never remove it for lack of sw_fini
interface. With this,driver will report create
sysfs fail when it's loaded for the second time.
