Subject: tests: add simple test cases for line iterators
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a39be20651b61794c3cd9071490b01f56631db69;p=qemu-gpiodev%2Flibgpiod.git

tests: add simple test cases for line iterators

We'll test them some more though after new functionalities in
gpio-mockup are released in kernel 4.11.
