* leds: ss4200: Fix incorrect placement of __initdataSachin Kamat2013-08-26
| | | | | | | | | __initdata should be placed between the variable name and equal sign for the variable to be placed in the intended section. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Cc: Dave Hansen <dave@sr71.net> Signed-off-by: Bryan Wu <cooloney@gmail.com>
* leds: leds-ss4200: Staticize nasgpio_led_get_attr()Jingoo Han2013-08-26
| | | | | | | | | | nasgpio_led_get_attr() is used only in this file. Fix the following sparse warning: drivers/leds/leds-ss4200.c:200:5: warning: symbol 'nasgpio_led_get_attr' was not declared.

* module_param: make bool parameters really bool (drivers & misc)Rusty Russell2012-01-12
| | | | | | | | | | | | module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version.

* leds: leds-ss4200: fix led_classdev_unregister twice in error handlingAxel Lin2010-05-26
| | | | | | | | | | | | | In current implementation, if device_create_file failed in register_nasgpio_led, led_classdev_unregister will be executed twice. ( in register_nasgpio_led it calls led_classdev_unregister before return and in nas_gpio_init out_err ) This patch fixes it by only unregistering those that were successfully registered in out_err.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The id_table field of the struct pci_driver is constant in <linux/pci.h> so it is worth to make pci_device_id also constant.

* leds: LED driver for Intel NAS SS4200 series (v5)Dave Hansen2009-12-16
This code is based on a driver that came in the "Open-source and GPL components" download here: http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Server+Products&ProductLine=Intel%C2%AE+Storage+Systems&ProductProduct=Intel%C2%AE+Entry+Storage+System+SS4200-E&OSVersion=OS+Independent It was in a file called nasgpio.c inside of a second zip file called SS4200-E_Linux_SIO_Driver-v1.4.zip and is based on this updated to use the LED subsystem with the ioctl and hardware monitor support removed. I don't have any need for brightness control, and its code is *completely* separate from the on/off controls implemented here. If anyone else wants it, I'd be happy to look into adding it, but I don't care enough for now. Except for the probe routines, I rewrote most of it. I also Note that I don't have any hardware documentation except for the original driver. Thanks go to Arjan for his help in getting the original source for this released and for chasing down some licensing issues.
