TPS65910 can be used even if interrupt is unused.
Hence let probe succeed in case interrupt can't be
configured and let Kernel only to complain about it

Hi Samuel,
I sent this yesterday, but did not reach LKML,
so assumed you also may not have recieved it;
resending.

Is there any potential issue when calling free_irq on a non-requested irq?
If it is, there should be a !irq check in tps65910_irq_exit or
tps65910_i2c_remove.
