Merge tag 'char-misc-3.17-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc driver fix from Greg KH:
"Here is one misc driver fix for 3.17-rc5. It resolves a kernel oops
that can happen in the lattice FPGA driver if the firmware isn't
present on the system.
It's been in the linux-next tree for a while now"
