From 2d26f6e39afb88d32b8f39e76a51b542c3c51674 Mon Sep 17 00:00:00 2001 From: Michael Riesch Date: Mon, 23 Aug 2021 16:37:54 +0200 Subject: [PATCH] net: stmmac: dwmac-rk: fix unbalanced pm_runtime_enable warnings This reverts commit 2c896fb02e7f65299646f295a007bda043e0f382 "net: stmmac: dwmac-rk: add pd_gmac support for rk3399" and fixes unbalanced pm_runtime_enable warnings. In the commit to be reverted, support for power management was introduced to the Rockchip glue code. Later, power management support was introduced to the stmmac core code, resulting in multiple invocations of pm_runtime_{enable,disable,get_sync,put_sync}. The multiple invocations happen in rk_gmac_powerup and stmmac_{dvr_probe, resume} as well as in rk_gmac_powerdown and stmmac_{dvr_remove, suspend}, respectively, which are always called in conjunction.
