Pointer which may have NULL value in some cases (depend on kernel configuration and GPIO method) is dereferenced later in code. I removed BUG() macro to do not halt code execution accoding to comments. And added WARN_ON() macro and exit from function if pointer "isr_reg" is NULL. Also compilation check is added for correct architecture configuration.
