From 7db08b2cb36cbfbcb06c44dc8e48ccb6a119466f Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Wed, 8 Nov 2017 16:34:54 -0500 Subject: ASoC: amd: use do_div rather than 64 bit division to fix 32 bit builds 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.
