gpiolib: Extract gpiod_not_found() helper
Several places in the code are using same idiom, i.e. IS_ERR(desc) && PTR_ERR(desc) == -ENOENT which meaning is GPIO description is not found. For better readability extract gpiod_not_found() helper and use it. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Bartosz Golaszewski <bgolaszewski@baylibre.com>
