Looks like you want regulator_bulk_get() here. Or (better yet though it'd be a potential issue for merge via MFD and the benefits aren't that exciting since you still need to disable) devm_regulator_bulk_get().
- ret = regulator_enable(twl6040->vio);
- if (ret != 0) {
dev_err(&client->dev, "Failed to enable VIO: %d\n", ret);
goto power_err;
- }
- ret = regulator_enable(twl6040->v2v1);
- if (ret != 0) {
dev_err(&client->dev, "Failed to enable V2V1: %d\n", ret);
regulator_disable(twl6040->vio);
goto power_err;
- }
Similarly regulator_bulk_enable() here, and it'll fix...
gpio1_err:
- regulator_disable(twl6040->v2v1);
- regulator_disable(twl6040->vio);
...the fact that if you fail to enable the v2.1 regulator you don't disable vio.
