hwmon: (gpio-fan) Remove un-necessary speed_index lookup for thermal hook

2016-02-20T01:14:25+00:00

Thermal hook gpio_fan_get_cur_state is only interested in knowing the current speed index that was setup in the system, this is already available as part of fan_data->speed_index which is always set by set_fan_speed. Using get_fan_speed_index is useful when we have no idea about the fan speed configuration (for example during fan_ctrl_init). When thermal framework invokes gpio_fan_get_cur_state=>get_fan_speed_index via gpio_fan_get_cur_state especially in a polled configuration for thermal governor, we basically hog the i2c interface to the extent that other functions fail to get any traffic out :(. Instead, just provide the last state set in the driver - since the gpio fan driver is responsible for the fan state immaterial of override, the fan_data->speed_index should accurately reflect the state.

hwmon: (dell-smm) Blacklist Dell Studio XPS 8000

2016-01-25T03:26:18+00:00

Since Linux 4.0 the CPU fan speed is going up and down on Dell Studio XPS 8000 and 8100 for unknown reasons. The 8100 was already blacklisted in commit a4b45b25f18d ("hwmon: (dell-smm) Blacklist Dell Studio XPS 8100"). This patch blacklists the XPS 8000. Without further debugging on the affected machine, it is not possible to find the problem.
