I have another question about i2c...

The 'sensors' program gives me a stange message:

w83627thf-i2c-9191-290
Can't get adapter name for bus 9191 <<<<<-----------------------------
VCore: +1.49 V (min = +1.94 V, max = +1.94 V) ALARM
+12.0V: +11.86 V (min = +10.82 V, max = +13.19 V)
+ 3.3V: +3.30 V (min = +3.14 V, max = +3.47 V)
...

And gnome-sensors-applet can't read the sensors. If using libsensors, no
value is displayed (I suppose an applicacion bug). And the access to sensors
directly through i2c-dev gives an error like this:

Error opening sensor device file:
/sys/devices/platform/i2c-9191/9191-0290/....

In fact, the real path is

/sys/devices/platform/i2c-adapter:i2c-9191/9191-0290/....

I supposed it was a kernel change not tracked by userspace, but the strange
thing is that looking at the code the sensors applet lists the sensors
reding directories and files in /sys (AFAICS in the code).
So perhaps there is a little inconsistency, /sys says in some place the
sensor is at xxxxx, when it really is at yyyyy.
Or the 'i2c-adapter:' is a bug and should be 'i2c-adapter/'.
