hi - I am compiling a rt kernel for my raspberry pi, and I notice I am unable to select the us122l driver for inclusion as a module as it is listed as requiring x86 to be selected.

Many of the other modules are available and use the same codebase as the us122l driver, so I was wondering if the x86 requirement is strictly necessary?

Is it possible to check that the us122l module requires x86 and is incompatible with arm architecture please.

The driver does a special way of mmap that may work only on the coherent architecture. It *might* work on ARM, so just try and give a patch if everything really works as expected.
