From 2e83a5c5d2317c386de2880eb43ef0bef8eb1fa9 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Wed, 15 Jul 2009 18:20:38 +0200 Subject: [PATCH] ds2760_battery: delay power supply registration This fixes a race condition I recently introduced with the PMOD feature addition (cef437e3: "w1: ds2760_battery: add support for sleep mode feature"). Postpone the call to power_supply_register() to fix it.
