====================
pull-request: can 2019-12-08
this is a pull request of 13 patches for net/master.
The first two patches are by Dan Murphy. He adds himself as a maintainer to the
m-can MMIO and tcan SPI driver.
The next two patches the j1939 stack. The first one is by Oleksij Rempel and
fixes a locking problem found by the syzbot, the second one is by me an fixes a
mistake in the documentation.
Srinivas Neeli fixes missing RX CAN packets on CANFD2.0 in the xilinx driver.
Sean Nyekjaer fixes a possible deadlock in the the flexcan driver after
suspend/resume. Joakim Zhang contributes two patches for the flexcan driver
that fix problems with the low power enter/exit.
The next 4 patches all target the tcan part of the m_can driver. Sean Nyekjaer
adds the required delay after reset and fixes the device tree binding example.
Dan Murphy's patches make the wake-gpio optional.
In the last patch Xiaolong Huang fixes several kernel memory info leaks to the
USB device in the kvaser_usb_leaf driver.
