Fixed typo and wrong sentence

[Federico Gimenez (fgimenez)]

Thanks Leo, it should be fixed now

START: /home/elopio/workspace/go/src/launchpad.net/snappy/_integration-tests/tests/hwAssign_test.go:48: hwAssignSuite.SetUpTest
fatal error: runtime: out of memory

That's because you are calling SetUpTest in SetUpTest.

The right call is:
s.SnappySuite.SetUpTest(c)

The same problem with tear down.

Sorry, it's fixed now.

Thanks!

+dev-kmsg snap
+
+This simple snap provides a binary to read and output real raw
+data from /dev/kmsg using dd. For it to work it needs that hw
+to be assigned before being run.
