module_param: make bool parameters really bool (drivers & misc)

2012-01-12T23:02:20+00:00

module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

x86: fix up files really needing to include module.h

2011-10-31T23:30:36+00:00

These files aren't just exporting symbols -- they are also defining
a MODULE_LICENSE etc. so give them the full module.h file.

WMI: properly cleanup devices to avoid crashes

2011-10-24T14:52:40+00:00

We need to remove devices that we destroy from the list, otherwise
we'll crash if there are more than one "_WDG" methods in DSDT.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=32052

WMI: return error if wmi_create_device() fails

2011-01-07T22:03:45+00:00

The break resets the retval to 0 but we want to return an error code.

WMI: Cater for multiple events with same GUID

2011-01-07T22:03:41+00:00

WMI data blocks can contain WMI events with the same GUID but with
different notifiy_ids, for example volume up/down hotkeys.
This patch enables a single event handler to be registered and
unregistered against all events with same GUID but different
notify_ids.  Since an event handler is passed the notify_id of
an event it can can differentiate between the different events.

The patch also ensures we only register and unregister a device per
unique GUID.

wmi: use memcmp instead of strncmp to compare GUIDs

2010-12-06T22:19:13+00:00

While looking for the duplicates in /sys/class/wmi/, I couldn't find
them. The code that looks for duplicates uses strncmp in a binary GUID,
which may contain zero bytes. The right function is memcmp, which is
also used in another section of wmi code.

It was finding 49142400-C6A3-40FA-BADB-8A2652834100 as a duplicate of
39142400-C6A3-40FA-BADB-8A2652834100. Since the first byte is the fourth
printed, they were found as equal by strncmp.

WMI: embed struct device directly into wmi_block

2010-10-21T13:36:48+00:00

Instead of creating wmi_blocks and then register corresponding devices
on a separate pass do it all in one shot, since lifetime rules for both
objects are the same. This also takes care of leaking devices when
device_create fails for one of them.

WMI: make use of class device's attributres

2010-10-21T13:36:48+00:00

Instead of adding modalias attribute manually set it up as class's
device attribute so driver core will create and remove it for us.
