Subject: [PATCH 1/2] iio:adc:qcom-spmi-vadc : fix undefined __divdi3
Date: Fri, 30 Dec 2016 18:25:49 +0000 [thread overview]
Message-ID: <20161230182550.12038-1-jic23@kernel.org> (raw)
A simple do_div call works here as all the signed 64 bit is
actually small and unsigned at this point, and the numerator is
u32.
