Subject: iio: tools: make generic_buffer look for "-trigger"
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=793d6b5ea80c9bba8de40b720991b436fa5e174d;p=openwrt%2Fstaging%2Fblogic.git

iio: tools: make generic_buffer look for "-trigger"

All the ST Sensors use the old "<foo>-trigger" rather than the
standard "<foo>-devN" new standard suffix for triggers. Now much
to do about it since it is ABI, but make the testing tools
recognize it too.
