  • 4f5b7994f   hwmon: (gpio-fan) Fix fan_ctrl_init error path ... Browse Code »

    In current implementation, the sysfs entries is not removed before return -ENODEV.

    Creating the sysfs attribute should be the last thing done by the function,
    after all the rest has been successful.
    Otherwise there is a small window during which user-space can access the attribute
    but the driver isn't ready to deal with the requests.

    Fix it by moving sysfs_create_group to be the last thing done by the function.

  • d6fe1360f   hwmon: add generic GPIO fan driver ... Browse Code »

    This patch adds hwmon support for fans connected to GPIO lines.

    Platform specific information such as GPIO pinout and speed conversion array
    (rpm from/to GPIO value) are passed to the driver via platform_data.
