From 313b9a9938bf4076425741121d5d766826793e5d Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Fri, 9 Sep 2016 09:31:54 +0100 Subject: gpio: pca953x: initialize ret to zero to avoid returning garbage ret is not initialized so it contains garbage. Ensure garbage is not returned in the case that pdata && pdata->teardown is false by initializing ret to 0.
