gpio: xgene-sb: Don't shadow error code of gpiochip_lock_as_irq()
gpiochip_lock_as_irq() may return a few error codes, do not shadow them by -ENOSPC and let caller to decide. No functional change intended. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
