Remove the assumption that driver_register() returns the number of devices
bound to the driver. In fact, it returns zero for success or a negative
error value.
dio_module_init() used the device count to automatically unregister and
unload drivers that found no devices. That might have worked at one time,
but has been broken for some time because dio_register_driver() returned
either a negative error or a positive count (never zero). So it could only
unregister on failure, when it's not needed anyway.
This functionality could be resurrected in individual drivers by counting
devices in their .probe() methods.

hysdn defines its own types: ulong, uint, uchar and word.
Problem is, the module_param macros rely upon some of those identifiers having

cannot be used in ISDN because of this namespace clash.
So remove the hysdn-private defines and open-code them all.

Because of historic reasons, there are two separate directories with
V4L stuff. Most drivers are located at driver/media/video. However, some
code for USB Webcams were inserted under drivers/usb/media.
This makes difficult for module authors to know were things should be.
Also, makes Kconfig menu confusing for normal users.
This patch moves all V4L content under drivers/usb/media to
drivers/media/video, and fixes Kconfig/Makefile entries.

This patch causes the network interface to respond to P_Key change
events correctly. As a result, you'll see a child interface in the
"RUNNING" state (netif_carrier_on()) only when the corresponding P_Key
is configured by the SM. When SM removes a P_Key, the "RUNNING" state
will be disabled for the corresponding network interface. To
implement this, I added IB_EVENT_PKEY_CHANGE event handling. To
prevent flushing the device before the device is open by the "delay
open" mechanism, I added an additional device flag called
IPOIB_FLAG_INITIALIZED.
This also prevents the child network interface from trying to join to
multicast groups until the PKEY is configured. We used to get error
messages like:
ib0.f2f2: couldn't attach QP to multicast group ff12:401b:f2f2:0:0:0:ffff:ffff
in this case. To fix this, I just check IPOIB_FLAG_OPER_UP flag in
ipoib_set_mcast_list().

Since the SCSI midlayer is moving towards entirely getting rid of
commands with use_sg == 0, we should treat this case as an exception.
Therefore, change the IB SRP initiator to create a fake scatterlist
for these commands with sg_init_one(). This simplifies the flow of
DMA mapping and unmapping, since SRP can just use dma_map_sg() and
dma_unmap_sg() unconditionally, rather than having to choose between
the dma_{map,unmap}_sg() and dma_{map,unmap}_single() variants.

Cleanup audio input handling in bttv and tvaudio:
- inputs were specified that were never used
- mute was handled as a special input which led to confusing code
- confusing naming made it difficult to see if the setting was for
i2c or gpio.
The old audiochip.h input names moved to tvaudio.h. Currently this
is used both by tvaudio and msp3400 until the msp3400 implements the
new msp3400-specific inputs.
Detect in bttv the tvaudio and msp3400 i2c clients and use these
client pointers to set the inputs directly instead of broadcasting the
command.
Removed AUDC_SET_INPUT. Now replaced by VIDIOC_S_AUDIO. This will be
replaced again later by the new ROUTING commands.
