From: Jarkko Nikula <jarkko.nikula@xxxxxxxxxxxxxxx> Platform drivers don't need dummy runtime PM callbacks that just return success in order to have runtime PM happening. This has changed since following commits: commit 05aa55dddb9e ("PM / Runtime: Lenient generic runtime pm callbacks") commit 543f2503a956 ("PM / platform_bus: Allow runtime PM by default") commit 8b313a38ecff ("PM / Platform: Use generic runtime PM callbacks directly") Signed-off-by: Jarkko Nikula <jarkko.nikula@xxxxxxxxxxxxxxx> Reviewed-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@xxxxxxxxxxx> Acked-by: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx> [shimoda: revise git commit description style] Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@xxxxxxxxxxx> --- drivers/usb/renesas_usbhs/common.c | 14 -------------- 1 file changed, 14 deletions(-) diff --git a/drivers/usb/renesas_usbhs/common.c b/drivers/usb/renesas_usbhs/common.c index a3e1290..0e760f2 100644 --- a/drivers/usb/renesas_usbhs/common.c +++ b/drivers/usb/renesas_usbhs/common.c @@ -874,23 +874,9 @@ static int usbhsc_resume(struct device *dev) return 0; } -static int usbhsc_runtime_nop(struct device *dev) -{ - /* Runtime PM callback shared between ->runtime_suspend() - * and ->runtime_resume().
