From 56fa18e8f1ef6b3995a4511e61103d0f9205ff4a Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Sun, 8 Jun 2008 19:43:42 +0400 Subject: power_supply: Fix race in power_supply_uevent Commit 54d29ad33e3483bcc7ca433a21cf294854e5154a (Power Supply: fix race in device_create) introduced a race in power_supply_uevent. Previously it checked that power_supply is available by checking for dev->driver_data. But now dev->driver_data is set before power_supply->dev is initialised.
