Applied to battery-2.6.git, thanks.

However, note that there's another issue that should be fixed
both in this driver and in the platform (or SPI device driver)
code.

Notice 'int irq' here.

So the irq number is derived from the platform device ID.
Which is very bizarre, and not how things supposed to work.
I guess there should be an IRQ resource for the device
instead.
