Subject: [PATCH AUTOSEL 5.4 03/22] media: budget-core: Improve exception handling in budget_register()
Date: Wed, 19 Aug 2020 20:02:10 -0400 [thread overview]
Message-ID: <20200820000229.215333-3-sashal@kernel.org> (raw)
In-Reply-To: <20200820000229.215333-1-sashal@kernel.org>
From: Chuhong Yuan <hslester96@gmail.com>
[ Upstream commit fc0456458df8b3421dba2a5508cd817fbc20ea71 ]
budget_register() has no error handling after its failure.
Add the missed undo functions for error handling to fix it.
