The descriptor list is walked in two points, in the bundle parsing and cport parsing, this can make the next descriptor pointer in bundle to be already removed by the cport remove descriptor and become invalid. So, just get the next bundle until there no more left. Signed-off-by: Rui Miguel Silva <rui.silva@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@google.com>

This is a major rework and changes to the current implementation of the battery protocol. The previous implementation lack the support of a more dynamic handle of power supply properties and updating of status. Also, reflect the actual state of the greybus specification So, with this new approach a set of operations to fetch the battery module configuration and properties is add, new methods to cache and update the values of properties, new operation to set properties if declared writable and an event operation that can be triggered by the module to force an update read on the properties values.

wIndex field has a special meaning, as that can be used by the core to index into the possible USB interfaces. And that specifically broke with gbsim, as it has a single USB interface. Other similar requests (REQUEST_LATENCY_TAG_{EN|DIS}) are already using wValue field for passing cport-id. Fix cport_reset() by sending the cport-id in wValue field instead of wIndex.

Fix host-device life time issues by separating host-device allocation from registration. This is needed both to make sure that all host-device resources are available before registering the device and to prevent such resources from being deallocated while the device is still in use during device removal. This specifically fixes the following warnings during es1 and es2 disconnect: usb 1-1.1: No free CPort OUT urbs, having to dynamically allocate one!

Add more structure to probe error handling rather than use the big hammer and call disconnect directly. This is needed to fix some host-device life-time issues. Note that there was never any need to clear the USB interface data as this will be done by driver core. Compile-only tested.

The current es2 implementation only checks for no IN or OUT bulk endpoints, but still assumes there are precisely NUM_BULKS of each. Specifically, urbs could be allocated and initialised to default values, which amounts to bulk urbs being submitted to the control endpoint. We should be able to handle any number of endpoints, but for now let's just require NUM_BULKS of each.
