Some recent hardware define more than 128 fields in the report
descriptor. Increase the limit to 256. This adds another kilobyte of
memory per report.

Hi Jiri,
The Flatfrog panel (next patch) reports 188 fields, so 256 seems like
a fair number. I am not overly thrilled about this patch, but the
alternative looks like a major change. At least it will be easy to
backport. :-)
Thanks,
Henrik
