Hi Andrew,

thanks for the review.

That's rather a lot of stack. Can this be made static, of kmalloced?


I think we'll made it static.

That's a bit rude - asking the compiler to perform a structure copy from an
odd address. memcpy() would be saner.

Could you elaborate a bit more ?
I don't see where there is a copy.
*cmvs is a pointer to the structure, not the structure. And when we parse the structure, we use get_unaligned functions.

People get shouted at for adding /proc handlers. Greg may have thoughts...

Ok, we may be convert some values to sysfs. It would be nice if usbatm allow us to export some common value (margin, ...).
