4.19-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit bff466bac59994cfcceabe4d0be5fdc1c20cd5b8 ]
Commit 3edfb7bd76bd ("gpiolib: Show correct direction from the beginning") fixed an existing issue but broke libgpiod tests by changing the default direction of dummy lines to output.
We don't break user-space so make gpio-mockup behave as before.
