Miller" , Sergei Shtylyov , linux-renesas-soc@vger.kernel.org, linux-usb@vger.kernel.org, Yoshihiro Shimoda , Jarkko Nikula List-Id: linux-i2c@vger.kernel.org Platform drivers don't need dummy runtime PM callbacks that just return success and non-NULL pm pointer in their struct device_driver in order to have runtime PM happening. This has changed since following commits: 05aa55dddb9e ("PM / Runtime: Lenient generic runtime pm callbacks") 543f2503a956 ("PM / platform_bus: Allow runtime PM by default") 8b313a38ecff ("PM / Platform: Use generic runtime PM callbacks directly") Signed-off-by: Jarkko Nikula --- Only build tested. --- drivers/i2c/busses/i2c-sh_mobile.c | 18 ------------------ 1 file changed, 18 deletions(-) diff --git a/drivers/i2c/busses/i2c-sh_mobile.c b/drivers/i2c/busses/i2c-sh_mobile.c index 818cab14e87c..a7a7a9c3bc7c 100644 --- a/drivers/i2c/busses/i2c-sh_mobile.c +++ b/drivers/i2c/busses/i2c-sh_mobile.c @@ -947,27 +947,9 @@ static int sh_mobile_i2c_remove(struct platform_device *dev) return 0; } -static int sh_mobile_i2c_runtime_nop(struct device *dev) -{ - /* Runtime PM callback shared between ->runtime_suspend() - * and ->runtime_resume().
