From 21e863b233553998737e1b506c823a00bf012e00 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Wed, 15 Oct 2014 16:25:10 +0200 Subject: [PATCH] power: bq2415x_charger: Fix memory leak on DTS parsing error Memory allocated for 'name' was leaking if required binding properties were not present. The memory for 'name' was allocated early at probe with kasprintf(). It was freed in error paths executed before and after parsing DTS but not in that error path. Fix the error path for parsing device tree properties.
