		irqreturn_t(*)(int irq, void *p)	pollfunc_bh,

iio_triggered_buffer_setup() - Setup triggered buffer and pollfunc : IIO device structure : Function which will be used as pollfunc bottom half : Function which will be used as pollfunc top half : Buffer setup functions to use for this device. If NULL the default setup functions for triggered buffers will be used.

This function combines some common tasks which will normally be performed when setting up a triggered buffer. It will allocate the buffer and the pollfunc, as well as register the buffer with the IIO core.

Before calling this function the indio_dev structure should already be completely initialized, but not yet registered. In practice this means that this function should be called right before iio_device_register().

To free the resources allocated by this function call iio_triggered_buffer_cleanup().
