From a54988113985ca22e414e132054f234fc8a92604 Mon Sep 17 00:00:00 2001 From: Gen Zhang Date: Wed, 29 May 2019 09:53:05 +0800 Subject: wcd9335: fix a incorrect use of kstrndup() In wcd9335_codec_enable_dec(), 'widget_name' is allocated by kstrndup(). However, according to doc: "Note: Use kmemdup_nul() instead if the size is known exactly." So we should use kmemdup_nul() here instead of kstrndup().
