Hello everybody!
I am trying to modify "pcspkr" driver undere linux kernel source tree. I added a new line there:
sample_id_dir = kobject_create_and_add("devices/platform/pcspkr/sample", NULL);
Ick, really? What are you trying to do with "raw" kobjects?
I am trying to add "read/write" attribute under "devices/platform/pcspkr". Just for educational purposes. Didn't find another way to do it.
Using a kobject is not how to do that at all, attributes need to be added to the structure that owns the directory. kobjects are a directory themselves. good luck! greg k-h
