[PATCH v2] ASoC: amd: move the call to devm_kzalloc below platform_get_resource()

From: Defang Bo
Date: Wed Oct 21 2020 - 03:37:41 EST


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.
