X-Git-Tag: firefly_0821_release~7613^2~3583^2~3^2~302 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=a7861ff082fe75fd7d7fd22c87c37c8425674ae2;p=firefly-linux-kernel-4.4.55.git staging: iio: max1363 fix bug due to scan_element directory move. The device found passed to the attr functions is that of the ring buffer, not the the iio_dev so we need to bounce through one more hop to get the right address.
