This reverts the mutex conversion that was recently done to the hdaps
driver; this coversion was buggy because the hdaps driver started using
this semaphore in IRQ context, which mutexes do not allow. Easiest
solution for now is to just revert the patch (the patch was part of a
bigger GIT commit, 9a61bf6300 but this
only reverts this one file)

Add required locking around idr_ routines, retry the idr_pre_get/idr_get_new
pair properly, and sprinkle in some likely/unlikely for good measure.
(Lack of idr locking didn't hurt when all callers were I2C clients, as the
i2c-core serialized for us anyway. Now that we have non I2C hwmon drivers,
this is truly necessary.)

Convert the f71805f driver to use arrays of attributes. This shrinks the
compiled module from 12.0 kB to 9.6 kB. We certainly should do the same
for as many hardware monitoring drivers as possible.
This, together with a nice chip design by Fintek, makes this driver
very small, both in terms of number of lines of code and memory
consumption.

Only scan I2C address 0x2d. This is the default address and no IT87xxF
chip was ever seen on I2C at a different address. These chips are
better accessed through their ISA interface anyway.
This fixes bug #5889, although it doesn't address the whole class
of problems. We'd need the ability to blacklist arbitrary I2C addresses
on systems known to contain I2C devices which behave badly when probed.
Plan the I2C interface for removal as well. If nobody complains within
a year, it will confirm my impression that the I2C interface isn't
actually needed by anyone.

This is my f71805f hardware monitoring driver ported from lm_sensors
to Linux 2.6. This new driver differs from the other hardware monitoring
drivers in that it is implemented as a platform driver. This might not
be optimal yet (we would probably need a generic infrastructure and bus
type for Super-I/O logical devices) but it is certainly much better than
the i2c-isa solution.
Note that this driver requires lm_sensors CVS. I hope to get it
released as 2.10.0 soon.

Just about every i2c chip driver sets the I2C_DF_NOTIFY flag, so we
can simply make it the default and drop the flag. If any driver really
doesn't want to be notified when i2c adapters are added, that driver
can simply omit to set .attach_adapter. This approach is also more
robust as it prevents accidental NULL pointer dereferences.
