Subject: bindings: cxx: tests: add a test case for chip::unwatch_line_info()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f2245fa32c1bccd171e53c579bd272a6d2c01c61;p=qemu-gpiodev%2Flibgpiod.git

bindings: cxx: tests: add a test case for chip::unwatch_line_info()

We don't have any test case for chip::unwatch_line_info() so add a simple
one similar to the one we have for the core C library.
