ACPI: add dynamic_debug support 2014-07-01T03:13:58+00:00 Bjørn Mork bjorn@mork.no 2014-05-22T10:47:47+00:00 e330441067f61822851ea4f58963525a498a9bde commit 45fef5b88d1f2f47ecdefae6354372d440ca5c84 upstream. Commit 1a699476e258 ("ACPI / hotplug / PCI: Hotplug notifications from acpi_bus_notify()") added debug messages for a few common events. These debug messages are unconditionally enabled if CONFIG_DYNAMIC_DEBUG is defined, contrary to the documented meaning, making the ACPI system spew lots of unwanted noise on any kernel with dynamic debugging. The bug was introduced by commit fbfddae69657 ("ACPI: Add acpi_handle_<level>() interfaces"), which added the CONFIG_DYNAMIC_DEBUG dependency without respecting its meaning.

commit 45fef5b88d1f2f47ecdefae6354372d440ca5c84 upstream.

Commit 1a699476e258 ("ACPI / hotplug / PCI: Hotplug notifications
from acpi_bus_notify()") added debug messages for a few common
events. These debug messages are unconditionally enabled if
CONFIG_DYNAMIC_DEBUG is defined, contrary to the documented
meaning, making the ACPI system spew lots of unwanted noise on
any kernel with dynamic debugging.

The bug was introduced by commit fbfddae69657 ("ACPI: Add
acpi_handle_<level>() interfaces"), which added the
CONFIG_DYNAMIC_DEBUG dependency without respecting its meaning.

Fix by adding real support for dynamic_debug.

When the thermal module is to be removed, we should destroy the wq
acpi_thermal_pm_queue after the ACPI driver's remove callback is
executed as we will need to flush the workqueue there, or a NULL pointer
access will be hit.
