Guenter Roeck 79da533d3c hwmon: (nct6775) Fix crash in clear_caseopen 
Paweł Marciniak reports the following crash, observed when clearing
the chassis intrusion alarm.

The problem is that the device passed to clear_caseopen() is the hwmon
device, not the platform device, and the platform data is not set in the
hwmon device. Store the pointer to sio_data in struct nct6775_data and
get if from there if needed.

Fixes: 2e7b988696 ("hwmon: (nct6775) Use superio_*() function pointers in sio_data.")
