| * regulator: tps65910: Fix using wrong dev argument for calling of_regulator_matchAxel Lin2013-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | The dev parameter is the device requesting the data. In this case it should be &pdev->dev rather than pdev->dev.parent. The dev parameter is used to call devm_kzalloc in of_get_regulator_init_data(), which means this fixes a memory leak because the memory is allocated every time probe() is called, thus it should be freed when this driver is unloaded.

| * | regulator: clear state each invocation of of_regulator_matchStephen Warren2013-01-29
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of_regulator_match() saves some dynamcially allocated state into the match table that's passed to it. By implementation and not contract, for each match table entry, if non-NULL state is already present, of_regulator_match() will not overwrite it. of_regulator_match() is typically called each time a regulator is probe()d. This means it is called with the same match table over and over again if a regulator triggers deferred probe. This results in stale, kfree()d data being left in the match table from probe to probe, which causes a variety of crashes or use of invalid data. Explicitly free all output state from of_regulator_match() before generating new results in order to avoid this.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current code does integer division (min_vol = min_uV / 1000) before pass min_vol to max8997_get_voltage_proper_val(). So it is possible min_vol is truncated to a smaller value. For example, if the request min_uV is 800900 for ldo. min_vol = 800900 / 1000 = 800 (mV) Then max8997_get_voltage_proper_val returns 800 mV for this case which is lower than the requested voltage. Use uV rather than mV in voltage_map_desc to prevent truncation by integer division.
