Subject: Staging: iio/dac/ad5360.c: signedness bug in ad5360_read_raw()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=685e010748f64a752a981254101e976d7291d16c;p=openwrt%2Fstaging%2Fblogic.git

Staging: iio/dac/ad5360.c: signedness bug in ad5360_read_raw()

ad5360_get_channel_vref() returns an int and scale_uv should be the
same.  Making it unsigned here breaks the error handling.
