X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=4d15307225ff15ed7352c01e570fdcca9bf0fe2c;p=users%2Fjedix%2Flinux-maple.git iio: adc: ti-ads131e08: Use new iio_push_to_buffers_with_ts() to provide length sanity check. By providing the size of the buffer used, runtime checks can be performed to ensure not overrun. Also change the pushed data pointer to be that of the structure that also contains the timestamp. Not an actual bug but semantically incorrect to push the channel data when we want the storage with the timestamp as well.
