regulator: s5m8767: Properly handle gpio_request failure Convert to devm_gpio_request to save a few error handling code. This patch properly handle the gpio_request failure, we should return error when gpio_request fails rather than just show warning. I think one of the reason we got -EBUSY is because current code does not free gpios in s5m8767_pmic_remove(). So it got -EBUSY when reload the module. Yest another reason is in current code if gpio_request() returns error, the rest of the code still calls gpio_direction_output to config buck_gpios and buck_ds gpios. This looks wrong to me.
