to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git

Subject: iio: mma8452: Fix ignoring MMA8452_INT_DRDY

Interrupts are ignored if no event bit is set in the status status register and this breaks the buffer interface. No data is shown when running "iio_generic_buffer -n mma8451 -a" and interrupt counts go crazy.

Fix by not returning IRQ_NONE if DRDY is set.
