X-Git-Tag: submit/tizen/20160405.082219~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ceced8d60a803304d206441f44606e4316d3318c;p=platform%2Fkernel%2Flinux-exynos.git

kdbus: TEST_CREATE_CONN now does no depend on TEST_CREATE_BUS

Without this patch, it is impossible to specify test case able to
connect to a bus already created (e.g. by 'test-daemon' test case), you can
only specify:

1) TEST_CREATE_BUS which creates new bus, or
2) TEST_CREATE_CONN OR'ed with TEST_CREATE_BUS which creates new bus and
creates connection to it.

This patch adds the missing ability to specify TEST_CREATE_CONN alone.

It will be used by a new test case (will be added by separate commit) which
is supposed to connect to already started test-daemon case.
