It does not work with the 3.16 kernel even when firmware is in
/lib/firmware, it worked before this patch is applied.
Here is what I got in my dmesg :
[    0.307856] __allocate_fw_buf: fw-lattice-ecp3.bit buf=bd81a480
[    0.308029] lattice-ecp3 spi2.3: Direct firmware load for
lattice-ecp3.bit failed with error -2
[    0.308078] __fw_free_buf: fw-lattice-ecp3.bit buf=bd81a480 data=
(null) size=0
[    0.308094] lattice-ecp3 spi2.3: Cannot load firmware, aborting

If you want specific messages, please tell me.

Thanks,
