Thank you very much for your response. I am relatively new to kernel development.

I know we can use kmalloc for memory allocation. Please advice.

struct es_em_ctxt ctxt = kmalloc(sizeof(struct es_em_ctxt), GFP_KERNEL);

I am thinking to update like above, but like you mentioned, ctxt is not a pointer. I can update this to be a pointer if needed.

Thanks,
