Marco,

I have a question regarding your patch.

I have TS-7260 board that I purchased back in 2007.  I wrote the
application that reads data on SPI bus (the application reads
digitized signal from ADC chip).  It turned out that SPI often is
missing few samples (which makes recorded data invalid)

I am wondering if your patch would help me to resolve this problem?
I don't have much experience with Linux, so if you think that your
patch will help, what do I need to do to install patch on my board?
