[Linux-stable-mirror] [PATCH] irqchip/gic-v3: fix ppi-partitions lookup

by Johan Hovold

Fix child-node lookup during initialisation, which ended up searching the whole device tree depth-first starting at the parent rather than just matching on its children. To make things worse, the parent giq node was prematurely freed, while the ppi-partitions node was leaked.

This adds support for the following PEAK-System CAN FD interfaces: PCAN-cPCIe FD CAN FD Interface for cPCI Serial (2 or 4 channels) PCAN-PCIe/104-Express CAN FD Interface for PCIe/104-Express (1, 2 or 4 ch.)

[Linux-stable-mirror] Patch "can: c_can: don't indicate triple sampling support for D_CAN" has been added to the 4.13-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled can: c_can: don't indicate triple sampling support for D_CAN to the 4.13-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: can-c_can-don-t-indicate-triple-sampling-support-for-d_can.patch and it can be found in the queue-4.13 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From fb5f0b3ef69b95e665e4bbe8a3de7201f09f1071 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Richard=20Sch=C3=BCtz?= <rschuetz(a)uni-koblenz.de> Date: Sun, 29 Oct 2017 13:03:22 +0100 Subject: can: c_can: don't indicate triple sampling support for D_CAN MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit From: Richard Schütz <rschuetz(a)uni-koblenz.de> commit fb5f0b3ef69b95e665e4bbe8a3de7201f09f1071 upstream. The D_CAN controller doesn't provide a triple sampling mode, so don't set the CAN_CTRLMODE_3_SAMPLES flag in ctrlmode_supported. Currently enabling triple sampling is a no-op.
