From 9761dca68c66f6e1305f9c3d5bb5a054512050b3 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Sun, 28 Feb 2016 19:57:58 +0000 Subject: [PATCH] power_supply: 88pm860x_charger: do not pass NULL to power_supply_put In the case where power_supply_get_by_name returns NULL the current error return path calls power_supply_put with a NULL psy which will cause a null pointer dereference. Avoid this with an immediate return.
