This is for the Asahi Kasei AK8975 3-axis magnetometer. It resides within
the magnetometer section of the IIO subsystem, and implements the raw
magn_x,y,z_raw attributes, as well as magn_x,y,z_scale attributes for
converting to Gauss.
Changed to use the magn_x,y,z_scale attributes, and made those attributes
give the scale factor to conert to Gauss. Also applied more fixes from
feedback.
Keeping mode as an unsigned long. I'm going to add proper power management
at some point anyway, which would deprecate this attribute.

Per email exchange with Jonathan Cameron, GAIN should instead be SCALE, to
be consistent with documentation.
Resending, since this goes with the 2/2 patch.

i2c_smbus_read_byte_data() returns an s32 type. We need to change
"rate" to signed for the error handling to work.
Also I changed it to propogate the error code instead of just returning
-EINVAL. Other error codes could be -EAGAIN for example.

Adjust the error handling code so that it benefits from the call to
mutex_unlock at the end of the function.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@rcu exists@
position p1;
expression E;
@@
mutex_lock@p1(E);
...
mutex_unlock(E);
@exists@
position rcu.p1;
expression E;
@@
*mutex_lock@p1(E);
... when != mutex_unlock(E);
?*return ...;
// </smpl>
