macintosh/hwmon/ams: Fix device removal sequence

2010-02-03T06:39:49+00:00

Some code that is in ams_exit() (the module exit code) should instead
be called when the device (not module) is removed. It probably doesn't
make much of a difference in the PMU case, but in the I2C case it does
matter.

I make no guarantee that my fix isn't racy, I'm not familiar enough
with the ams driver code to tell for sure.

hwmon: (ams) Fix locking issues

2008-10-17T15:51:12+00:00

Use a separate mutex to serialize input device creation/removal,
otheriwse we deadlock if we try to remove input device while it is
being polled. Also do not take ams_info.lock when it is not needed.

hwmon: (ams) Fix permissions on 'joystick' module parameter

2008-10-17T15:51:12+00:00

We should not allow writes to the 'joystick' module parameters since
writing there will not trigger creation of the input device. Disable
writes since we provide alternative way of enabling input device via
AMS device's sysfs attribute.

hwmon: (ams) Convert to a new-style i2c driver

2008-10-17T15:51:12+00:00

The legacy i2c binding model is phasing out, so the ams driver needs
to be converted to a new-style i2c driver. Here is a naive approach of
this conversion. Basically it is moving the i2c device creation from
the ams driver to the i2c-powermac driver. This should work, but I
suspect we could come up with something cleaner by declaring the i2c
device as part of the platform setup. This could be done later by
someone more familiar with openfirmware-based platforms than I am
myself.

One nice thing brought by this conversion is that the ams driver
should be loaded automatically on systems where is is needed (at
least when the I2C interface to the chip is used) providing
coldplug-aware user-space environment.
