Subject: [PATCH] iio:adc:qcom-spmi-vadc: use div64_s64 instead of direct 64 bit division.
Date: Sun, 8 Jan 2017 21:06:29 +0000 [thread overview]
Message-ID: <20170108210629.17725-1-jic23@kernel.org> (raw)
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.
Signed-off-by: Jonathan Cameron <jic23@kernel.org>
