Subject: tests: mockup: make sure the gpio-mockup debugfs directory is writable
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b434907c5e587dd366836ce5c7fa4194ae78345f;p=qemu-gpiodev%2Flibgpiod.git

tests: mockup: make sure the gpio-mockup debugfs directory is writable

The gpio-mockup library needs write permissions to make full use of
the debugfs interface. Add the W_OK flag to the call to access() when
preparing the context structure.
