The separation between algorithm and adapter was unsharp at places. This was
partly hidden by the fact, that the ISA-driver allowed just one instance and
had all private data in static variables. This patch makes neccessary
preparations to add a platform driver on top of the algorithm, while still
supporting ISA. Note: Due to lack of hardware, the ISA-driver could not be
tested except that it builds.
Concerning the core struct i2c_algo_pca_data:
- A private data field was added, all hardware dependant data may go here.
Similar to other algorithms, now a pointer to this data is passed to the
adapter's functions. In order to make as less changes as possible to the
ISA-driver, it leaves the private data empty and still only uses its static
variables.
- A "reset_chip" function pointer was added; such a functionality must come
from the adapter, not the algorithm.
- use a variable "i2c_clock" instead of a function pointer "get_clock",
allowing for write access to a default in case a wrong value was supplied.
In the algorithm-file:
- move "i2c-pca-algo.h" into "linux/i2c-algo-pca.h"
- now using per_instance timeout values (i2c_adap->timeout)
- error messages specify the device, not only the driver name
- restructure initialization to easily support "i2c_add_numbered_adapter"
- drop "retries" and "own" (i2c address) as they were unused
(The state-machine for I2C-communication was not touched.)
In the ISA-driver:
- adapt to new algorithm

This patch adds release callback support, which is called when a bsg
device goes away. bsg_register_queue() takes a pointer to a callback
function. This feature is useful for stuff like sas_host that can't
use the release callback in struct device.
If a caller doesn't need bsg's release callback, it can call
bsg_register_queue() with NULL pointer (e.g. scsi devices can use
release callback in struct device so they don't need bsg's callback).
With this patch, bsg uses kref for refcounts on bsg devices instead of
get/put_device in fops->open/release. bsg calls put_device and the
caller's release callback (if it was registered) in kref_put's
release.

The current target allocation code registeres each possible target
with sysfs; it will be deleted again if no useable LUN on this target
was found. This results in a string of 'target add/target remove' uevents.
Based on a patch by Hannes Reinecke <hare@suse.de> this patch reworks
the target allocation code so that only uevents for existing targets
are sent. The sysfs registration is split off from the existing
scsi_target_alloc() into a in a new scsi_add_target() function, which
should be called whenever an existing target is found. Only then a
uevent is sent, so we'll be generating events for existing targets
only.

We have a problem in scsi_transport_spi in that we need to customise
not only the visibility of the attributes, but also their mode. Fix
this by making the is_visible() callback return a mode, with 0
indicating is not visible.
Also add a sysfs_update_group() API to allow us to change either the
visibility or mode of the files at any time on the fly.

potentially causing a buffer overflow and/or confusing the caller

This is preliminary since:
1. It supports only _one_ chip select at the moment. As there is no
existing platforms available using two chip selects of the NAND
controller, it shall really not include code for supporting the
2nd chip select for now, as such code cannot be verified.
2. It resorts to the default and simpliest memory based badblock
table
3. Only limited types of nand flash are currently supported. Most
PXA3xx processors come with on-chip NAND flash dies, so there
isn't much flexibility for other types of NAND.
4. The NAND controller should be configured to detect the device's
ID, thus making it difficult to use nand_scan_ident() to assist
the detection process (though it's not impossible)

Microsoft's wireless desktop receiver (Model 1028) has a bug in the report
descriptor -- namely, in four seperate places it uses USAGE_MIN and _MAX when
it quite obviously doesn't intend to.
In other words, it reports that it has pretty much _everything_ in 'consumer'
and 'generic desktop'. And then the X evdev driver believes I have a mouse
with 36 absolute axes and a huge pile of keys and buttons, when I in fact,
should have zero. 255/256 in three of the cases, and 0-1024 in another.
This patch fixes the report descriptor of this device before it enters the HID
