Subject: iio:light:cm3323: replace unneeded variable
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=0ff8c78df8d7c32394b887de4d935962a7f373ce;p=deliverable%2Flinux.git

iio:light:cm3323: replace unneeded variable

In cm3323_read_raw() i is used as return variable for the integration time
index. The also existing return variable ret however is unused in this
case, although appropriate. Replace i with ret and drop it.
