From 3e61c4fab13ff1d7b62a2fdfa2b2b4b943389607 Mon Sep 17 00:00:00 2001 From: chenqiwu Date: Fri, 7 Feb 2020 17:46:39 +0800 Subject: [PATCH] pstore/platform: fix potential mem leak if pstore_init_fs failed [ Upstream commit 8a57d6d4ddfa41c49014e20493152c41a38fcbf8 ] There is a potential mem leak when pstore_init_fs failed, since the pstore compression maybe unlikey to initialized successfully. We must clean up the allocation once this unlikey issue happens.
