From e30eca0e69cb888125b081c96ca761e958fcb5b4 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Sun, 8 Jan 2017 19:52:25 +0000 Subject: [PATCH] iio:adc:qcom-spmi-vadc: use div64_s64 instead of direct 64 bit division. Another one of these that we missed previously which prevents test builds of this driver on 32 bit platforms as it gives an undefined __divdi3 warning.
