    leds-lp5521: modify the way of setting led device name · 61a83932

    Currently the led device name is fetched from the device_type in
    I2C_BOARD_INFO which comes from the platform data.  This name is in turn
    used to create an entry in sysfs.
    If there exists two or more lp5521 on a particular platform, the
    device_type in I2C_BOARD_INFO has to be the same, else lp5521 driver probe
    wont be called and if used so, results in run time warning "cannot create
    sysfs with same name" and hence a failure.
    The name that is used to create sysfs entry is to be passed by the struct
    led_platform_data.  Hence adding an element of type const char * and
    change in lp5521 driver to use this name in creating the led device if
    present else use the name obtained by I2C_BOARD_INFO.
