From 54e82f5c9a21b52f99daf4465c3039e2901406ff Mon Sep 17 00:00:00 2001 From: Lech Perczak Date: Tue, 11 Jan 2022 00:13:02 +0100 Subject: ath79: kernel: drop _machine_restart again Backport patch ("MIPS: ath79: drop _machine_restart again"), which is required to support GPIO restart handler on ZTE MF286, broken due to _machine_restart being restored in kernel accidentally, wich causes any registered restart handlers to not execute, including one from ath79-reset driver.
