Subject: xenbus_transaction_end() returns negative error code.
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~16770^2~1^2
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/%22/%22http:/www.example.com/cgi/%22?a=commitdiff_plain;h=f61d64c62e3945c1f9b18c4917e16f7d7c7556e2;p=xen.git

xenbus_transaction_end() returns negative error code.
Therefore need to test for -EAGAIN (not EAGAIN).
