Subject: [PATCH] iio: kfifo: Set update_needed to false only if a buffer was
 allocated

Check whether the allocation of a new kfifo buffer failed or not before
setting the update_needed flag to false. This will make
iio_request_update_kfifo() try to allocate a new buffer the next time a
buffer update is requested.
