The current implementation does not accept this sequence on a given mdio
bus: register/unregister/register.
The device core framework complain about already initialized kobject
struct:
"kobject (df9e9848): tried to init an initialized object, something is
seriously wrong."

If the hub_configure() fails after setting the hdev->maxchild
the hub->ports might be NULL or point to uninitialized kzallocated
memory causing NULL pointer dereference in hub_quiesce() during cleanup.
Now after such error the hdev->maxchild is set to 0 to avoid cleanup
of uninitialized ports.
Si
After successful initialization hub->descriptor->bNbrPorts and
hub->hdev->maxchild are equal, but using hub->hdev->maxchild is
preferred because that value is explicitly used for initialization
of hub->ports[].

Hi,
this series fixes hub_configure() error handling that causes hub->ports[i]
NULL pointer dereferences.
Changes in v3:
Added Acked-by from Alan Stern.
Changes in v2:
After review by Alan Stern. The new label has been placed in other place
to avoid changes in existing code. Third patch "usb:
These patches add missing of_node_put() to fix reference leak or
iounmap in setup/probe error path.

Some multitouch screens do not like to be polled for input reports.
However, the Win8 spec says that all touches should be sent during
each report, making the initialization of reports unnecessary.
The Win7 spec is less precise, so do not use this for those devices.
Add the quirk HID_QUIRK_NO_INIT
Ignoring usb_hub_create_port_device() errors cause later NULL pointer
deference when uninitialized hub->ports[i] entries are dereferenced
after port memory allocation error.

Hi guys,
this is the v3 of this patch series.
Srinivas, I still did not added your tested-by as I made minors modifications of
the patches 1 and 2. Now only the patch 1 will impact sensor_hub, and patch 2
will not impact this. Maybe just wait for Henrik to put his "Reviewed-by" before
giving one
Detecting Win 8 multitouch devices in core allows us to set quirks
before the device is parsed through hid_hw_start().
It also simplifies the detection of those devices in hid-multitouch and
makes the handling of those devices cleaner.
As Win 8 multitouch panels are in the group multitouch and rel

The Win 8 detection is sufficiently complex to warrant use of the full
parser code, in spite of the inferred memory usage. Therefore, we can use
the existing HID parser in hid-core for hid_scan_report() by re-using the
code from hid_open_report(). hid_parser_global, hid_parser_local and
hid_parser_

Sage,
Thanks. If you run into any problems please let me know and I'll
resolve them quick and I'll make sure I'm watching the qa mailing
list.
