If that's needed and is done, you can add my tag for: Reviewed-by: Bhaumik Bhatt <bbhatt@codeaurora.org> We can just push this patch as a standalone one not dependent on the 1/2 in this series.

Since M3 can be entered/exited quite a lot when used for runtime PM, keep the mhi suspend/resume transitions quiet. Signed-off-by: Loic Poulain <loic.poulain@linaro.org> --- drivers/bus/mhi/core/pm.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) -- 2.7.4
