print_mac() used many most net drivers and format_addr() used by
net-sysfs.c are very similar and they can be intergrated.
format_addr() is also identically redefined in the qla4xxx iscsi
driver.
Export a new function sysfs_format_mac() to be used by net-sysfs,
qla4xxx and others in the future. Both print_mac() and
sysfs_format_mac() call _format_mac_addr() to do the formatting.
Changed print_mac() to use unsigned char * to be consistent with
net_device struct's dev_addr. Added buffer length overrun checking
as suggested by Joe Perches.

This patch does three things. It modifies tg3_setup_flow_control() to
use the administrator requested flow control settings if
autonegotiation is turned off. It slightly modifies the
tg3_setup_fiber_mii_phy() function to account for this new use case.
And finally, it does the same for tg3_setup_copper_phy().
The copper modifications are more than a small multi-line change. The
new code makes an attempt to avoid a link renegotiation if the link is
active at half duplex and the only difference between the current
advertised settings and requested advertised settings is the
flow control advertisements.

Introduce scan capabilities to WEXT so that userspace can do intelligent

If the driver reports a specific scan capability, the driver must
respect the options specified in the iw_scan_req structure when handling
the SIOCSIWSCAN call, unless it's mode or state does not allow it to do
so, in which case it must return an error.

Samsung USB remotes (0419:0001) are rejected by kernel 2.6.23, because the
report descriptor from the remote contains a 48 bit HID report field. HID 1.11
states: Fields may span at most 4 bytes.
This patch, based on 2.6.23, fixes this by modifying the internal report
descriptor in hid-quirks.c. Additional user space support (e.g. LIRC) is
required to fetch the information from the hiddev interface.
The burden to reconstruct the data is moved into userspace (lirc through hiddev).
There is no need to set HID_QUIRK_HIDDEV quirk, as the device has also output
applications, which trigger the creation of hiddev device automatically.

The device is not discoverable, and needs to be poked to set its master, the
Bluetooth device it will try to connect to when the "Home" button is pressed
without a cable plugged in.
Using libusb means disconnecting the device from its driver to get the report
descriptor. Using hiddev, we can poke it without relinquishing control over it,
so when you plug it in, it would still work as a pad.
This could be then used by sixpair program, after it is rewritten to use

smc91x is shared between many different platforms. Each platform needs
to specify the interrupt type, and in some cases the irq type depends
on more than just the build configuration - it depends on runtime
checks.
Rather than throwing this code into the SMC_IRQ_FLAGS definition, provide
a way for these flags to be passed via the IRQ resource itself.
Note that IRQF_TRIGGER_* constants are intentionally defined to correspond
with the IORESOURCE_IRQ_* interrupt type flags, in much the same way that
the low bits of PCI iomem resources correspond with the BAR flag bits.
Also provide a way to configure smc91x to read the IRQ flags from the
resource. Once all platforms have been converted over (signified
by all definitions of SMC_IRQ_FLAGS being -1) SMC_IRQ_FLAGS should
be removed.

This patch converts xsysace to use blk_end_request interfaces.
Related 'uptodate' arguments are converted to 'error'.
xsysace is a little bit different from "normal" drivers.
xsysace driver has a state machine in it.
It calls end_that_request_first() and end_that_request_last()
from different states. (ACE_FSM_STATE_REQ_TRANSFER and
ACE_FSM_STATE_REQ_COMPLETE, respectively.)
However, those states are consecutive and without any interruption
inbetween.
So we can just follow the standard conversion rule (b) mentioned in
the patch subject "[PATCH 01/30] blk_end_request: add new request
completion interface".

This patch converts ide-cd (cdrom_newpc_intr()) to use blk_end_request
interfaces. Related 'uptodate' arguments are converted to 'error'.
In PIO mode, ide-cd (cdrom_newpc_intr()) needs to defer
end_that_request_last() until the device clears DRQ_STAT and raises
an interrupt after end_that_request_first().
So blk_end_request() has to return without completing request
even if no leftover in the request.
ide-cd uses blk_end_request_callback() and a dummy callback function,
which just returns value '1', to tell blk_end_request_callback()
about that.

This patch converts "normal" parts of ide to use blk_end_request
interfaces. Related 'uptodate' arguments are converted to 'error'.
The conversion of 'uptodate' to 'error' is done only for the internal
function, __ide_end_request().
ide_end_request() was not changed since it's exported and used
by many ide drivers.
With this patch, blkdev_dequeue_request() in __ide_end_request() is
moved to blk_end_request, since blk_end_request takes care of
dequeueing request like below:
if (!list_empty(&rq->queuelist))
blkdev_dequeue_request(rq);
In the case of ide,
o 'dequeue' variable of __ide_end_request() is 1 only when the request
is still linked to the queue (i.e. rq->queuelist is not empty)
o 'dequeue' variable of __ide_end_request() is 0 only when the request
has already been removed from the queue (i.e. rq->queuelist is empty)
So blk_end_request can handle it correctly although ide always run
thought the code above.

The i2c_adapter.clients list of i2c_client nodes duplicates driver
model state. This patch starts removing that list, letting us remove
most existing users of those i2c-core lists.
* The core I2C code now iterates over the driver model's list instead
of the i2c-internal one in some places where it's safe:
- Passing a command/ioctl to each client, a mechanims
used almost exclusively by DVB adapters;
- Device address checking, in both i2c-core and i2c-dev.
* Provide i2c_verify_client() to use with driver model iterators.
* Flag the relevant i2c_adapter and i2c_client fields as deprecated,
to help prevent new users from appearing.
For the moment the list needs to stick around, since some issues show
up when deleting devices created by legacy I2C drivers. (They don't
follow standard driver model rules. Removing those devices can cause
self-deadlocks.)
