    iio: accel: fxls8962af: Fix use after free in fxls8962af_fifo_flush

    fxls8962af_fifo_flush() uses indio_dev->active_scan_mask (with
    iio_for_each_active_channel()) without making sure the indio_dev
    stays in buffer mode.
    There is a race if indio_dev exits buffer mode in the middle of the
    interrupt that flushes the fifo. Fix this by calling
    synchronize_irq() to ensure that no interrupt is currently running when
    disabling buffer mode.
