The omap3isp driver hides is power management functions using #ifdef but it fails to hide the isp_suspend_modules/isp_resume_modules functions in the same way, which leads to a build warning when CONFIG_PM is disabled: drivers/media/platform/omap3isp/isp.c:1183:12: error: 'isp_suspend_modules' defined but not used [-Werror=unused-function] drivers/media/platform/omap3isp/isp.c:1217:13: error: 'isp_resume_modules' defined but not used [-Werror=unused-function] As the driver manually defines its dev_pm_ops structure and all members are NULL without CONFIG_PM, we can simply avoid referencing the structure using an IS_ENABLED() check, and drop all the #ifdef to avoid all warnings.
