From c6738d06a363ac7010a5c3b54e2af1957852cc45 Mon Sep 17 00:00:00 2001 From: Chanwoo Choi Date: Tue, 26 Aug 2014 13:41:38 +0900 Subject: [PATCH] power: charger-manager: Fix checking of wrong return type This patch fix minor issue about checking wrong return type. The of_cm_parse_desc() return ERR_PTR(errnor number) when some error happen in this function. But, charger_manager_probe() has only checked whether desc is NULL or not. If of_cm_parse_desc() returns ERR_PTR(-ENOMEM), desc isn't NULL but desc is (void *)(-ENOMEM). Althouhg some error happen for parsing DT, charger_manager_probe() can't detect error of desc instance.
