No, I'm not sure that it is for the 2.6.21 kernel. I've searched around for
i2c-2p93xx.patch and 2.6.21 kernel and the only results I find are...questions
I've posted 6 months ago. Yeah.
If I try all of this with a different kernel, won't I simply run into similar
problems when I try to configure that kernel for the TS-7350 (when I run 'make
ts7350_defconfig')?
