Hi,

Here is second version of patch which fixes bug in
/arch/arm/plat-omap/gpio.c file.
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.

Thanks,
Evgeny
