Subject: staging: iio: generic_buffer: initialize ret
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=11cb454f092397b8cb1ba478efaa5743bea604a2;p=openwrt%2Fstaging%2Fblogic.git

staging: iio: generic_buffer: initialize ret

The `ret´ variable is only initialized in the error case. For some reason
it was always != 0 while I played with generic_buffer so here is a patch.
