From 39d183d87791cdfd9d430df299396c0fc688ea7a Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Thu, 13 Dec 2007 15:54:45 +1100 Subject: [POWERPC] Convert therm_pm72.c to use the kthread API This converts the therm_pm72.c driver to use the kthread API. I thought about making it use kthread_stop() instead of the `state' variable and the `ctrl_complete' completion, but that isn't simple and will require changing the way that `state' is used.
