The pty code has always been buggy on its ldisc handling. The recent

properly which is not at all trivial, at least make the race small again so
we don't disrupt other dev work.

We depend up on the pwm_enable register (0x96) not containing any reserved
settings in various places. We were already checking to make sure there
were no reserved settings in the register for the f71862fg, this patch adds
the same checking for the f8000, while at it it also moves the code to
a more apropriate place so we don't need to check if the fan/pwm part
of the IC is enabled twice.

Currently we are using separate per model sysfs attr for the 3th pwm, because
the 3th pwm of the f8000 only has automatic mode and not manual mode. Doing
things this way was getting in the way for adding f71858fg support, so this
patch makes the pwm attr identical for all models, and instead adds a check
to store_pwm_enable() disallowing setting the 3th pwm to manual mode
on a f8000 IC.

The MSI MS-7031 is based on an ATI IXP300 south bridge. On this south
bridge, accessible I/O ports must be enabled explicitly. Unfortunately
the BIOS forgets to enable access to the hardware monitoring chip I/O
ports, so hardware monitoring fails.
Add a quirk enabling access to the required ports (0x295-0x296). This
is exactly what MSI's own hardware monitoring application is doing, so
it has to be the right way.

Thanks, but it turns out I hit a 32 bit integer overflow in

In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device. Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used. These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.
