- Current implementation tests wrong value for setting
aat2870_bl->max_current.
- In the current implementation, we cannot differentiate between 2 cases:
a) if pdata->max_current is not set , or
b) pdata->max_current is set to AAT2870_CURRENT_0_45 (which is also 0).
Fix it by setting AAT2870_CURRENT_0_45 to be 1 and adjust the equation in
aat2870_brightness() accordingly.
