patch "iio: accel: fxls8962af: return IRQ_HANDLED when fifo is flushed" added to staging-linus

[gregkh]

This is a note to let you know that I've just added the patch titled

    iio: accel: fxls8962af: return IRQ_HANDLED when fifo is flushed

to my staging git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-linus branch.

The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.

If you have any questions about this process, please let me know.

Subject: iio: accel: fxls8962af: return IRQ_HANDLED when fifo is flushed

fxls8962af_fifo_flush() will return the samples flushed.
So return IRQ_NONE only if an error is returned.
