Hi, I'm writing a i2c device driver. In probe(), among other things I call: polled_input = input_allocate_polled_device(); input_register_polled_device(polled_input); Then inside remove(), I extract the instance of input_polled_dev and call input_unregister_polled_device(polled_input); This results in kernel error: "Unable to handle kernel NULL pointer dereference at virtual address 00000474". It turns out that the input_dev pointer inside input_polled_dev is null which leads to this error. But why is input_dev pointer null? It is not null inside probe() function and I don't release it anywhere. This is code: http://pastebin.com/JJdepyEG and here is link to the output, along with my log statements: http://pastebin.com/badwSvyy.
