Description Wang, Zhenyu Z 2004-08-18 02:27:06 UTC 
Problem Description:
Current acpi thermal driver doesn't care about pending task
when deleteing timer. The acpi_thermal_check() will still be called
by pending task and may set up another timer for it, even if thermal
module has been removed. 
When remove thermal module, kfree(tz) should be called.
These issues are found by Li, Shaohua.
