This would overwrite the led classdev object previously registered by led_classdev_register(). Note that despite this mistake, the driver work fine because led_dat and led_dat->cdev are at the same memory address.

leds: leds-ns2: fix locking 2010-09-20T02:43:42+00:00 Simon Guinot sguinot@lacie.com 2010-09-19T13:30:59+00:00 f539dfedbd169e5ed47912bb517c75976ab556f3 This patch replace all the lock functions with the irq safe variant. The ns2_led_{set,get}_mode() functions must be safe in all context. For example, the trigger timer call led_set_brightness() in a softirq context.

leds: add LED driver for Network Space v2 LEDs 2010-07-17T02:02:00+00:00 Simon Guinot sguinot@lacie.com 2010-07-06T14:08:46+00:00 11efe71f6564e59ba9acfc636ac6f423e059dc69 This patch add a LED class driver for the dual-GPIO LEDs found on the Network Space v2 board (and parents). This include Internet Space v2, Network Space (Max) v2 and d2 Network v2 boards. This dual-GPIO LED is wired to a CPLD and can blink in relation with the SATA activity. The driver expose this capability through a "sata" sysfs attribute. Signed-off-by: Simon Guinot <sguinot@lacie.com> Signed-off-by: Nicolas Pitre <nico@fluxnic.net>
