In order to allow the report descriptor to influence the hid device
properties, one needs to parse the descriptor early, without reference
to any driver. Scan the descriptor for group information during device
add, before the device has been broadcast to userland. The device
modalias will contain group information which can be used to
differentiate between modules. For starters, just handle the generic
group.

HID devices are only partially presented to userland. Hotplugged
devices emit events containing a modalias based on the basic bus,
vendor and product entities. However, in practise a hid device can
depend on details such as a single usb interface or a particular item
in a report descriptor.
This patch adds a device group to the hid device id, and broadcasts it
using uevent and the device modalias. The module alias generation is
modified to match. As a consequence, a device with a non-zero group
will be processed by the corresponding group driver instead of by the
generic hid driver.

The low-level driver can read the report descriptor, but it cannot
determine driver-specific changes to it. The hid core can fixup
and parse the report descriptor during driver attach, but does
not have direct access to the descriptor when doing so.
To be able to handle attach/detach of hid drivers properly,
a semantic change to hid_parse_report() is needed. This function has
been used in two ways, both as descriptor reader in the ll drivers and
as a parsor in the probe of the drivers. This patch splits the usage
by introducing hid_open_report(), and modifies the hid_parse() macro
to call hid_open_report() instead. The only usage of hid_parse_report()
is then to read and store the device descriptor. As a consequence, we
can handle the report fixups automatically inside the hid core.

This patch finishes off adding full support for the TiVo Slide remote,
which is a mostly pure HID device from the perspective of the kernel.
There are a few mappings that use a vendor-specific usage page, and a
few keys in the consumer usage page that I think make sense to remap
slightly, to better fit their key labels' intended use. Doing this in a
stand-alone hid-tivo.c makes the modifications only matter for this
specific device.
What's actually connected to the computer is a Broadcom-made usb dongle,
which has an embedded hub, bluetooth adapter, mouse and keyboard
devices. You pair with the dongle, then the remote sends data that its
converted into HID on the keyboard interface (the mouse interface
doesn't do anything interesting, so far as I can tell).
lsusb for this device:
Bus 004 Device 005: ID 0a5c:2190 Broadcom Corp.
Bus 004 Device 004: ID 0a5c:4503 Broadcom Corp.
Bus 004 Device 003: ID 150a:1201
Bus 004 Device 002: ID 0a5c:4500 Broadcom Corp. BCM2046B1 USB 2.0 Hub (part of BCM2046 Bluetooth)
Speaking of the keyboard interface, the remote actually does contain a
keyboard as well. The top slides away, revealing a reasonably functional
qwerty keyboard (not unlike many slide cell phones), thus the product
name.

As part of the removal of get_driver()/put_driver(), this patch
(as1511) changes all the places that add dynamic IDs for drivers.
Since these additions are done by writing to the drivers' sysfs
attribute files, and the attributes are removed when the drivers are
unregistered, there is no reason to take an extra reference to the
drivers.
The one exception is the pci-stub driver, which calls pci_add_dynid()
as part of its registration. But again, there's no reason to take an
extra reference here, because the driver can't be unloaded while it is
being registered.
