pull-request: can 2014-11-18

[Marc Kleine-Budde <mkl@pengutronix.de>]

Hello David,

this is a pull request of 17 patches for net/master for the v3.18 release
cycle.

The last patch of this pull request ("can: m_can: update to support CAN FD
features") adds, as the description says, a new feature to the m_can driver. As
the m_can driver has been added in v3.18 there is no risk of causing a
regression. Give me a note if this is not okay and I'll create a new pull
request without it.

There is a patch for the CAN infrastructure by Thomas Körper which fixes
calling kfree_skb() from interrupt context. Roman Fietze fixes a typo also in
the infrastructure. A patch by Dong Aisheng adds a generic helper function to
tell if a skb is normal CAN or CAN-FD frame. Alexey Khoroshilov of the Linux
Driver Verification project fixes a memory leak in the esd_usb2 driver. Two
patches by Sudip Mukherjee remove unused variables and fixe the signess of a
variable. Three patches by me add the missing .ndo_change_mtu callback to the
xilinx_can, rcar_can and gs_usb driver.

The remaining patches improve the m_can driver: David Cohen adds the missing
CONFIG_HAS_IOMEM dependency. Dong Aisheng provides 6 bugfix patches (most
important: missing RAM init, sleep in NAPI poll, dlc in RTR). While the last of
his patches adds CAN FD support to the driver.

regards,
Marc
