+Subject: [PATCH] bindings: cxx: tests: set direction when reconfiguring lines
+
+Linux kernel commit b44039638741 ("gpiolib: cdev: Ignore reconfiguration
+without direction") made the direction setting mandatory for line config
+passed to the kernel when reconfiguring requested lines. Fix the C++ test
+case which doesn't do it and now fails due to the rest of the settings
+being ignored.
