stable request: 4.20.y: ASoC: soc-core: fix init platform memory handling

Hi Greg,

While testing v4.20.y on Tegra I noticed that the kernel is crashing on boot if certain sound-cards are probe deferred. This issue has been fixed in the mainline by the following commit ...

commit 09ac6a817bd687e7f5dac00470262efdd72f9319 Author: Curtis Malainey cujomalainey@chromium.org Date: Thu Jan 10 16:21:04 2019 -0800

ASoC: soc-core: fix init platform memory handling

I have verified that this applies cleanly and resolves the issue on v4.20.y. Please can we include for the v4.20.y stable branch?

Cheers Jon
