Re: Driver for the ST LIS302DL MEMS motion sensor

[Paul Goyette <paul%whooppee.com@localhost>]

I've not seen any i2c devices use iic_establish_intr() before, so I 
wonder if that will actually work.  You should probably check to see if 
your i2c controller even implements interrupt handling - I don't 
remember seeing any...

It might not make much sense here, but most sensors are actually polled 
(via sysmon_envsys calls to the device's xxx_refresh() routine).  You 
might want to provide a xxx_refresh() anyway (and set the timer value).
