From 3bbbf150ffde2ca48249537d2d9e4b52bc0a5fc8 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 4 Jun 2012 11:36:22 +0200 Subject: [PATCH] staging:iio:dac:ad5504: Use strtobool for boolean values Use strtobool for parsing the powerdown value instead of strict_strtol, since the powerdown attribute is a boolean value.
