This patch adds the sysfs class "hwmon" for use by hardware monitoring
(sensors) chip drivers.  It also fixes up the related Kconfig/Makefile
bits.

Drop the separate client name for the LM78-J chip. This is really
only a later revision of the LM78, with almost no difference and
no difference the driver handles in any case.

This was the only client name that had a dash in it, and special care
had to be taken in libsensors because of it. As we plan to write a new
library soon, I'd like to get rid of this exception before we do.

As a nice side effect, it saves 876 bytes in lm78.ko.

The LM75 initialization is a bit agressive, it arbitrarily reconfigures
the chip. Make it only change the bit it needs. This is a port from
the 2.4 kernel version of the driver (lm_sensors).

This patch fixes several instances of hwmon drivers kfree'ing the "wrong"
pointer; the existing code works somewhat by accident.

(akpm: plucked from Greg's queue based on lkml discussion.  Finishes off the
patch from Jon Corbet)

Coverity uncovered an off-by-one error in the fscpos driver, in function
set_temp_reset(). Writing to the temp3_reset sysfs file will lead to an
array overrun, in turn causing an I2C write to a random register of the
FSC Poseidon chip. Additionally, writing to temp1_reset and temp2_reset
will not work as expected. The fix is straightforward.

The adm9240 driver, in adm9240_detect(), allocates a structure.  The
error path attempts to kfree() ->client field of it (second one),
resulting in an oops (or slab corruption) if the hardware is not present.

->client field in adm1026, adm1031, smsc47b397 and smsc47m1 is the first in
${HWMON}_data structure, but fix them too.

A few split string in i2c (and now hwmon) drivers lack a joining space,
causing them to display incorrectly. This trivial patch fixes that up.

Part 2: Move the driver files themselves.

Note that the patch "adds trailing whitespace", because it does move the
files as-is, and some files happen to have trailing whitespace.
