From 9aa5134ac486b48c4c8ac14571e6034131f040f8 Mon Sep 17 00:00:00 2001 From: Rodrigo Siqueira Date: Fri, 9 Mar 2018 20:46:25 -0300 Subject: [PATCH] staging:iio:ad2s1210: Remove old_data from ad2s1210_state The variable old_data is a bool type, which only receives the value 'true' in the function ad2s1210_config_write and ad2s1210_config_read. There is no other use for this variable. This patch removes old_data from the ad2s1210_state and from all the function that use it.
