gpio: mockup: Switch to use kasprintf_strarray()
Since we have a generic helper, switch the module to use it. No functional change intended. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Acked-by: Bartosz Golaszewski <brgl@bgdev.pl> Reviewed-by: Linus Walleij <linus.walleij@linaro.org>
