From a390d1f379cf821248b735f43d2e1147ebb8241d Mon Sep 17 00:00:00 2001 From: Marcin Slusarz Date: Fri, 13 Mar 2009 15:41:19 -0700 Subject: phylib: convert state_queue work to delayed_work It closes a race in phy_stop_machine when reprogramming of phy_timer (from phy_state_machine) happens between del_timer_sync and cancel_work_sync. Without this change it could lead to crash if phy_device would be freed after phy_stop_machine (timer would fire and schedule freed work).
