Subject: [PATCH] [led] Misc fixes in the driver code
|
||
|
|
to_bundle returned the wrong data. The platform_device is the
|
||
|
|
parent of the class_device used by the LED device class. Return
|
||
|
|
the correct class.
|
||
|
|
|
||
|
|
num_leds was not set to the correct number of registered LEDs. All
|
||
|
|
loops using num_leds (e.g. module unloading) were not executed at
|
||
|
|
all.
|
||
|
|
|
||
|
|
On removal of the module disable all LEDs.
