From: Rodrigo Siqueira Date: Fri, 9 Mar 2018 23:46:25 +0000 (-0300) Subject: staging:iio:ad2s1210: Remove old_data from ad2s1210_state X-Git-Tag: v4.17-rc1~124^2~205^2 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9aa5134ac486b48c4c8ac14571e6034131f040f8;p=thirdparty%2Flinux.git 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.
