This is a note to let you know that I've just added the patch titled
slimbus: ngd: set correct device for pm
to my char-misc git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git
in the char-misc-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: slimbus: ngd: set correct device for pm
For some reason we ended up using wrong device in some places for pm_runtime calls.
Fix this so that NGG driver can do runtime pm correctly.
