SIMPLE_PM_DEV_OPS() is deprecated according to <linux/pm.h>.
Use DEFINE_SIMPLE_PM_DEV_OPS() instead. This avoids a build warning
when CONFIG_PM is not enabled:

drivers/extcon/extcon-max14526.c:265:12: warning: ‘max14526_resume’ defined but not used [-Wunused-function]
  265 | static int max14526_resume(struct device *dev)

Fixes: c2aeb8647e53 ("extcon: Add basic support for Maxim MAX14526 MUIC")

Hi,

In order to keep the consistent style of extcon patches,
I'd like you to edit the patch title as following:
- As-Is: extcon: Maxim MAX14526: avoid defined but not used warning
- To-Be: extcon: max14526: avoid defined but not used warning
