Subject: [PATCH v2] ASoC: amd: move the call to devm_kzalloc below platform_get_resource()
Date: Wed, 21 Oct 2020 15:03:02 +0800	[thread overview]
Message-ID: <1603263782-8711-1-git-send-email-bodefang@126.com> (raw)
In-Reply-To: <broonie@kernel.org>

Just as the commit <4cb79ef9c6c4>("ASoC: amd: Fix potential NULL pointer dereference"),it makes no sense to allocate any resources if platform_get_resource fails,so move the call to devm_kzalloc() below the mentioned code.
