Use devm_hid_hw_start_and_open helper to ensure that hid resources are consistent with the device life cycle, and release hid resources before device is released. At the same time, it can avoid the goto-release encoding, drop the out_hw_close and out_hw_stop lables, and directly return the error code when an error occurs. Further optimization, use devm_hwmon_device_register_with_info to replace hwmon_device_register_with_info, the remote operation can be completely deleted, and the drvdata no longer needs to hold hwmon device Acked-by: Guenter Roeck Signed-off-by: Li Zetao --- v2 -> v3: None v2: https://lore.kernel.org/all/20240909012313.500341-16-lizetao1@huawei.com/ v1 -> v2: 1) Further optimize using devm_hwmon_device_register_with_info and remove the .remove operation 2) Adjust commit information v1: https://lore.kernel.org/all/20240904123607.3407364-20-lizetao1@huawei.com/ drivers/hwmon/nzxt-smart2.c | 38 +++++-------------------------------- 1 file changed, 5 insertions(+), 33 deletions(-) diff --git a/drivers/hwmon/nzxt-smart2.c b/drivers/hwmon/nzxt-smart2.c index df6fa72a6b59..9c6d020ac896 100644 --- a/drivers/hwmon/nzxt-smart2.c +++ b/drivers/hwmon/nzxt-smart2.c @@ -172,7 +172,6 @@ struct set_fan_speed_report { struct drvdata { struct hid_device *hid; - struct device *hwmon; u8 fan_duty_percent[FAN_CHANNELS]; u16 fan_rpm[FAN_CHANNELS]; @@ -730,6 +729,7 @@ static int nzxt_smart2_hid_probe(struct hid_device *hdev, const struct hid_device_id *id) { struct drvdata *drvdata; + struct device *hwmon; int ret; drvdata = devm_kzalloc(&hdev->dev, sizeof(struct drvdata), GFP_KERNEL); @@ -750,44 +750,17 @@ static int nzxt_smart2_hid_probe(struct hid_device *hdev, if (ret) return ret; - ret = hid_hw_start(hdev, HID_CONNECT_HIDRAW); + ret = devm_hid_hw_start_and_open(hdev, HID_CONNECT_HIDRAW); if (ret) return ret; - ret = hid_hw_open(hdev); - if (ret) - goto out_hw_stop; - hid_device_io_start(hdev); init_device(drvdata, UPDATE_INTERVAL_DEFAULT_MS); - drvdata->hwmon = - hwmon_device_register_with_info(&hdev->dev, "nzxtsmart2", drvdata, - &nzxt_smart2_chip_info, NULL); - if (IS_ERR(drvdata->hwmon)) { - ret = PTR_ERR(drvdata->hwmon); - goto out_hw_close; - } - - return 0; - -out_hw_close: - hid_hw_close(hdev); - -out_hw_stop: - hid_hw_stop(hdev); - return ret; -} - -static void nzxt_smart2_hid_remove(struct hid_device *hdev) -{ - struct drvdata *drvdata = hid_get_drvdata(hdev); - - hwmon_device_unregister(drvdata->hwmon); - - hid_hw_close(hdev); - hid_hw_stop(hdev); + hwmon = devm_hwmon_device_register_with_info(&hdev->dev, "nzxtsmart2", drvdata, + &nzxt_smart2_chip_info, NULL); + return PTR_ERR_OR_ZERO(hwmon); } static const struct hid_device_id nzxt_smart2_hid_id_table[] = { @@ -807,7 +780,6 @@ static struct hid_driver nzxt_smart2_hid_driver = { .name = "nzxt-smart2", .id_table = nzxt_smart2_hid_id_table, .probe = nzxt_smart2_hid_probe, - .remove = nzxt_smart2_hid_remove, .raw_event = nzxt_smart2_hid_raw_event, #ifdef CONFIG_PM .reset_resume = nzxt_smart2_hid_reset_resume,
