Hmm... fixing the bug I mentioned in my other email this still
seems to cause some problems with my SPI on Cragganmore:

[  200.210213] wm0010 spi0.0: I/O Error: rx-1 tx-1 res:rx-f tx-f len-2632
[  200.211275] wm0010 spi0.0: SPI transfer failed: -5

I am still looking into it, without your patches work the wm0010
comes up. A few other small things seem to have been broken in
mainline since last time I fired up this board as well which is
slowing me down a little (network seems to have stopped coming
up and one of the regulators on the SD card is spamming me with
warnings).

Thanks,
Charles
