Hi John, For patches that go to a soc maintainer for merge, we're asking that people don't cc [email protected] directly.
We prefer to keep that alias mostly for pull requests from other maintainers and patches we might have a reason to apply directly. Otherwise we risk essentially getting all of linux-arm-kernel into this mailbox as well. Thanks! -Olof On Thu, Jun 20, 2019 at 11:33 AM John Garry <[email protected]> wrote: > > As reported in [1], the hisi-lpc driver has certain issues in handling > logical PIO regions, specifically unregistering regions. > > This series add a method to unregister a logical PIO region, and fixes up > the driver to use them. > > RCU usage in logical PIO code looks to always have been broken, so that > is fixed also.
