From 2490594e89c7286585daeaf05a06b6cd7b5c8876 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 4 Jun 2012 11:36:23 +0200 Subject: [PATCH] staging:iio:dac:ad5624r: Use strtobool for boolean values Use strtobool for parsing the powerdown value instead of strict_strtol, since the powerdown attribute is a boolean value.
