The DSPI interrupt can be shared between two controllers at least on the LX2160A. In that case, the driver for one controller might misbehave and consume the other's interrupt. Fix this by actually checking if any of the bits in the status register have been asserted.It would be better to have done this as the first patch before the restructuring, that way we could send this as a fix - the refactoring while good doesn't really fit with stable.
