From 804486b19de92449203f95027c2b207d8c5d5c79 Mon Sep 17 00:00:00 2001 From: Milo Kim Date: Tue, 25 Aug 2015 14:54:12 +0900 Subject: [PATCH] regulator: lp872x: handle error case If memory allocation gets failed on parsing the DT, then it returns error '-ENOMEM' explicitly. Then, the driver exists from the _probe().
