Subject: app/eventdev: fix possible uninitialized variable
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=ff0633d2b1b9457261528de739da0f4c0fe83b32;p=dpdk.git

app/eventdev: fix possible uninitialized variable

When compiling with -O1, this error can appear:
	app/test-eventdev/test_pipeline_common.c:332:6: error:
	‘ret’ may be used uninitialized in this function

If there is no device, then ret is returned without being initialized.
It is fixed by setting 0 as initial value.

Fixes: 032a965a8f1d ("app/eventdev: support Tx adapter")
