[PATCH 1/2] platform/x86/drivers/acerhdf: Use module_param_cb to set/get polling interval

[Daniel Lezcano]

The module parameter can be set by using ops to get and set the
values. The change will allow to check the correctness of the interval
value everytime it is changed instead of checking in the get_temp
function.
