With gcc 7.3.0:
gpio-mockup-chardev.c: In function ‘get_debugfs’:
gpio-mockup-chardev.c:62:3: warning: ignoring return value of ‘asprintf’, declared with attribute warn_unused_result [-Wunused-result]
asprintf(path, "%s/gpio", mnt_fs_get_target(fs));
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Handle asprintf() failures to fix this.

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.

This test script try to do whitebox testing for gpio subsystem(based on
gpiolib). It manipulate gpio device through chardev or sysfs and check
the result from debugfs. This script test gpio-mockup through chardev by
default. User could test other gpio chip by passing the module name.
Some of the testcases are turned off by default to avoid the conflicting
with gpiochip in system.
In details, it test the following things:
1. Test direction and output value for valid pin.
2. Test dynamic allocation of gpio base.
3. Add single, multi gpiochip to do overlap check.
Run "tools/testing/selftests/gpio/gpio-mockup.sh -h" for usage.
