Subject: [PATCH AUTOSEL 4.14 15/39] x86/unwind/orc: Fix error path for bad ORC entry type
Date: Thu, 14 May 2020 14:54:32 -0400 [thread overview]
Message-ID: <20200514185456.21060-15-sashal@kernel.org> (raw)
In-Reply-To: <20200514185456.21060-1-sashal@kernel.org>
From: Josh Poimboeuf <jpoimboe@redhat.com>
[ Upstream commit a0f81bf26888048100bf017fadf438a5bdffa8d8 ]
If the ORC entry type is unknown, nothing else can be done other than
reporting an error. Exit the function instead of breaking out of the
switch statement.
Fixes: ee9f8fce9964 ("x86/unwind: Add the ORC unwinder")
