Linus, Bartosz,
This was discovered during our investigations of a functional tests regression/error:
https://bugs.linaro.org/show_bug.cgi?id=3769
Which turned out to be related to missing CONFIG_ARM{64}_MODULE_PLTS config in our builds.
However, during investigations, we realized the functional test had the issues best described in comment:
https://bugs.linaro.org/show_bug.cgi?id=3769#c3
Related to errno variable being considered outside the error scope.
Thank you Rafael

Following logic from commit: 22f6592b23, GPIOHANDLE_REQUEST_OUTPUT should handle errors same way as GPIOHANDLE_REQUEST_INPUT does, or else the following error occurs:
gpio-mockup-chardev: gpio<gpiochip1> line<0> test flag<0x2> value<0>: No such file or directory
despite the real result of gpio_pin_test(), gpio_debugfs_get() and gpiotools_request_linehandle() functions.

Bartosz, does this look OK to you?
Yours, Linus Walleij
