From 3248c0892da13ffd05275c86edd2a3287b931962 Mon Sep 17 00:00:00 2001 From: Wenwen Wang Date: Fri, 9 Aug 2019 23:29:48 -0500 Subject: ALSA: hda - Fix a memory leak bug commit cfef67f016e4c00a2f423256fc678a6967a9fc09 upstream. In snd_hda_parse_generic_codec(), 'spec' is allocated through kzalloc(). Then, the pin widgets in 'codec' are parsed. However, if the parsing process fails, 'spec' is not deallocated, leading to a memory leak. To fix the above issue, free 'spec' before returning the error.
