I added that SPI select patch for 3.17-rc1 and it was removed right 
after I got bug report it should not be there. But there was of course 
some delay and removal patch went to 3.17-rc6.

But all in all, it was all happening during 3.17 period and I wonder how 
it could affect you?

Here are related discussions:
