This is a note to let you know that I've just added the patch titled
PCI: endpoint: Fix kernel panic after put_device()
to the 4.14-stable tree which can be found at:
http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git%3Ba=su...
The filename of the patch is: pci-endpoint-fix-kernel-panic-after-put_device.patch and it can be found in the queue-4.14 subdirectory.
If you, or anyone else, feels it should not be added to the stable tree, please let stable@vger.kernel.org know about it.
This patch is the 2nd one of a series of patches. If you want to add it to the stable tree without the first patch, you must add a
+ kfree(func_name);
before returning from the function.
The upstream commit of the first patch is 36cc14ac14c0d49d33820a82dab52a7edc802fef PCI: endpoint: Simplify name allocation for EPF device
Kind regards, Rolf

[ Upstream commit 9eef6a5c3b0bf90eb292d462ea267bcb6ad1c334 ]
'put_device()' calls the relase function 'pci_epf_dev_release()', which already frees 'epf->name' and 'epf'.
Therefore we must not free them again after 'put_device()'.
Fixes: 5e8cb4033807 ("PCI: endpoint: Add EP core layer to enable EP controller and EP functions")
