Date: Thu, 27 Mar 2014 20:56:55 +0900 From: Chanwoo Choi <cw00.choi@...sung.com> To: dbaryshkov@...il.com, dwmw2@...radead.org Cc: myungjoo.ham@...sung.com, kyungmin.park@...sung.com, linux-kernel@...r.kernel.org, Chanwoo Choi <cw00.choi@...sung.com> Subject: [RESEND PATCH] 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.
