Hi Rafael,
Apparently, I have queued an mmc patch in my mmc tree, which means one
mmc driver starts using the SET_PM_RUNTIME_PM_OPS macro. It should
cause a build error in linux-next with @subject patch.
I have shared that patch through an immutable branch, I have also
checked potential conflicts and it shouldn't be any problems to pull
that in to your tree. Then you can fix $subject patch by also
converting the mmc driver to use SET_RUNTIME_PM_OPS macro.
The branch is available at:
git://git.linaro.org/people/ulf.hansson/mmc.git mmc_for_linux_pm
Kind regards
Uffe
