Subject[PATCH 5/6] staging: rtl: Use existing define with polynomial
Date
Do not define again the polynomial but use header with existing define.

Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
---
Not tested

It would be nice to get some testing. Only generic lib/crc, bunzip, xz_crc32
and Freescale's Ethernet driver were tested on HW. Rest got just different
builds.
