PNP: Avoid leaving unregistered device objects in lists

2015-03-18T21:40:04+00:00

pnp_register_protocol() and __pnp_add_device() both have a problem that if device_register() fails, the objects they create will be left in the lists they have been put one beforehand. Unfortunately, that is not handled by the callers of those routines either, so in case of a device registration errors the PNP bus type's data structures will end up in an inconsistent state. Make pnp_register_protocol() and __pnp_add_device() remove the objects from the lists if device registration fails. Signed-off-by: Rafael J. Wysocki

PNP: Convert pnp_lock into a mutex

2015-03-18T21:39:55+00:00

pnp_lock is a spinlock, but it is only acquired from process context, so it may be a mutex just fine. Signed-off-by: Rafael J. Wysocki

PNP: Set up pnp_debug via module and not via boot param.

2010-10-27T06:23:59+00:00

Cleanup only, no functional change (pnp.debug can be enabled and disabled at runtime, but that's not a real enhancement). This one depends on another PNP cleanup patch: PNP: Compile all pnp built-in stuff in one module namespace Signed-off-by: Thomas Renninger Signed-off-by: Bjorn Helgaas Signed-off-by: Len Brown

PNP: log PNP resources, as we do for PCI

2010-10-01T05:59:34+00:00

ACPI devices are often involved in address space conflicts with PCI devices, so I think it's worth logging the resources they use. Otherwise we have to depend on lspnp or groping around in sysfs to find them. Signed-off-by: Bjorn Helgaas Signed-off-by: Len Brown

PNPACPI: Add support for remote wakeup

2010-07-18T23:58:48+00:00

This patch (as1354) adds remote-wakeup support to the pnpacpi driver. The new can_wakeup method also allows other PNP protocol drivers (pnpbios or iaspnp) to add wakeup support, but I don't know enough about how they work to actually do it.
