How to find platform_device entry from a kernel module
Folks, I have a 3.10.12 kernel and have written a character device driver as a loadable kernel module. From within this driver I want to find a particular device, an LED, that I want to blink as I operate. This LED was registered using "platform_device_reqister". What I would like to do is enumerate all of the devices registered in this manner and find the one I want, but, I have been unable to discover how to start. There is a lot of documentation on the kernel objects, but nothing I can find on how to find a particular one.
I thank any responders in advance!
