Marc Kleine-Budde says:

====================
this is a pull request for net/master, for the v3.15 release cycle, consisting
of 26 patches.

Thomas Gleixner contributes 21 patches for the c_can driver, which address
several shortcomings in the driver like hardware initialisation, concurrency,
message ordering and poor performance. Two patches Oliver Hartkopp, one adds a
missing lock to the sja1000_isa driver, the other one fixes the return value in
the generic bit time configuration function. And finally a patch by Alexander
Stein, that fixes the slcan driver to use the correct spinlock variant.

To make it 26 patches, Wolfgang Grandegger patch for the c_can_pci
driver, which enables the bus master only for MSI and a patch by
Wolfram Sang, which converts the 'instance' in the c_can driver to the
proper type.
