This is a note to let you know that I've just added the patch titled
devres: fix devres_get()
to my driver-core git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git
in the driver-core-testing 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 be merged to the driver-core-next branch sometime soon,
after it passes testing, and the merge window is open.
If you have any questions about this process, please let me know.

Subject: devres: fix devres_get()
Currently, devres_get() passes devres_free() the pointer to devres,
but devres_free() should be given with the pointer to resource data.
Fixes: 9ac7849e35f7 ("devres: device resource management")
