Change the chip id definition and detection and then:
1. We no longer need to add PM800_CHIP_XXX for the coming revision.
2. We no longer need to pass driver_data in i2c_device_id as we
can distinguish the chips from the CHIP_ID register.

SCTP_STATIC is just another define for the static keyword. It's use
is inconsistent in the SCTP code anyway and it was introduced in the
initial implementation of SCTP in 2.5. We have a regression suite in
lksctp-tools, but this is for user space only, so noone makes use of
this macro anymore. The kernel test suite for 2.5 is incompatible with
the current SCTP code anyway.
So simply Remove it, to be more consistent with the rest of the kernel
code.

The Tegra EHCI driver directly calls various functions in the Tegra USB
PHY driver. The reverse is also true; the PHY driver calls into the EHCI
driver. This is problematic when the two are built as modules.
The calls from the PHY to EHCI driver were originally added in commit
bbdabdb "usb: add APIs to access host registers from Tegra PHY", for the
following reasons:
1) The register being touched is an EHCI register, so logically only the
EHCI driver should touch it.
2) (1) implies that some locking may be needed to correctly implement the
r/m/w access to this shared register.
3) We were expecting to pass only the PHY register space to the Tegra PHY
driver, and hence it would not have access to touch the shared
registers.
To solve this, that commit added functions in the EHCI driver to touch the
shared register on behalf of the PHY driver.
In practice, we ended up not having any locking in the implementaiton of
those functions, and I've been led to believe this is safe. Equally, (3)
did not happen either. Hence, it is possible for the PHY driver to touch
the shared register directly.
Given that, this patch moves the code to touch the shared register back
into the PHY driver, to eliminate the module problems. If we actually
need locking or co-ordination in the future, I propose we put the lock
support into some pre-existing core module, or into a third separate
module, in order to avoid the circular dependencies.
I apologize for my contribution to code churn here.

We had the limit of 255 USB to serial devices on one system for almost
15 years, with no complaints. But now it's time to move on from these
tiny "baby" systems, and bump the number up to 512, which should last
us a few more years:
"512 is a nice number" -- Tobias Winter
Note, this is still a static value, and uses up tty core memory with
this many tty devices allocated. Converting the driver to use
TTY_DRIVER_DYNAMIC_DEV is the next thing to do in order to remove this
limitation.

This moves the allocation of minor device numbers from a static array to
be dynamic, using the idr interface. This means that you could
potentially get "gaps" in a minor number range for a single USB serial
device with multiple ports, but all should still work properly.
We remove the 'minor' field from the usb_serial structure, as it no
longer makes any sense for it (use the field in the usb_serial_port
structure if you really want to know this number), and take the fact
that we were overloading a number in this field to determine if we had
initialized the minor numbers or not, and just use a flag variable
instead.
Note, we still have the limitation of 255 USB to serial devices in the
system, as that is all we are registering with the TTY layer at this
point in time.

minimum_to_wake is unique to N_TTY processing, and belongs in
per-ldisc data.
Add the ldisc method, ldisc_ops::fasync(), to notify line disciplines
when signal-driven I/O is enabled or disabled. When enabled for N_TTY
(by fcntl(F_SETFL, O_ASYNC)), blocking reader/polls will be woken
for any readable input. When disabled, blocking reader/polls are not
woken until the read buffer is full.
Canonical mode (L_ICANON(tty), n_tty_data::icanon) is not affected by
the minimum_to_wake setting.

the ring
Backends may need to protect themselves against an insane number of
produced requests stored by a frontend, in case they iterate over
requests until reaching the req_prod value. There can't be more
requests on the ring than the difference between produced requests
and produced (but possibly not yet published) responses.

It is counter-intuitive to have "0" mean disable in a boolean
manner for electronic properties of pins such as pull-up and
pull-down. Therefore, define that a pull-up/pull-down argument
of 0 to such a generic option means that the pin is
short-circuited to VDD or GROUND. Pull disablement shall be
done using PIN_CONFIG_BIAS_DISABLE.

The use of current_norm to keep track of the current standard has been
deprecated for quite some time. Now that all drivers that were using it
have been converted to use g_std we can drop it from the core.
It was a bad idea to introduce this at the time: since it is a per-device
node field it didn't work for drivers that create multiple nodes, all sharing
the same tuner (e.g. video and vbi nodes, or a raw video node and a compressed
video node). In addition it was very surprising behavior that g_std was
implemented in the core. Often drivers implemented both g_std and current_norm,
because they didn't understand how it should be used.
Since the benefits were very limited (if they were there at all), it is better
to just drop it and require that drivers just implement g_std.
