This, of course, should have been #ifdef CONFIG_PM. Fixed v3 below. Thanks, Josh -- 8< -- Subject: [PATCH v3] usb: phy: msm: fix compilation errors when !CONFIG_PM_SLEEP Both the PM_RUNTIME and PM_SLEEP callbacks call into the common msm_otg_{suspend,resume} routines, however these routines are only being built when CONFIG_PM_SLEEP. In addition, msm_otg_{suspend,resume} also depends on msm_hsusb_config_vddcx(), which is only built when CONFIG_PM_SLEEP. Fix the CONFIG_PM_RUNTIME, !CONFIG_PM_SLEEP case by changing the preprocessor conditional, and moving msm_hsusb_config_vddcx(). While we're here, eliminate the CONFIG_PM conditional for setting up the dev_pm_ops. This address the following errors Russell King has hit doing randconfig builds: drivers/usb/phy/phy-msm-usb.c: In function 'msm_otg_runtime_suspend': drivers/usb/phy/phy-msm-usb.c:1691:2: error: implicit declaration of function 'msm_otg_suspend' drivers/usb/phy/phy-msm-usb.c: In function 'msm_otg_runtime_resume': drivers/usb/phy/phy-msm-usb.c:1699:2: error: implicit declaration of function 'msm_otg_resume' Cc: Ivan T.
