Hi Vijendar,

Below is the patch from Guenter Roeck groeck@chromium.org to fix build errors on 32 bit.

Regards, Akshu

From 3aa3a8549e986d860300e0623d048ec93482da19 Mon Sep 17 00:00:00 2001 From: Guenter Roeck groeck@chromium.org Date: Fri, 22 Sep 2017 09:43:27 -0700 Subject: [PATCH] FIXUP: FROMLIST: ASoC: amd: Report accurate hw_ptr during dma

ERROR: "__aeabi_uldivmod" [sound/soc/amd/snd-soc-acp-pcm.ko] undefined!

64-bit divides require special operations to avoid build errors on 32-bit systems.
