Marc Kleine-Budde says:

====================
this is a pull request of three patches for net-next/master.

Oleg Moroz added support for a new PCI card to the generic SJA1000 PCI
driver, Guenter Roeck's patch limits the flexcan driver to little
endian arm (and powerpc) and I fixed a sparse warning found by the
kbuild robot in the ti_hecc driver.
