Subject: staging: vt6656: ETHbIsBufferCrc32Ok replace CRCdwGetCrc32
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=a06978bc6d3877783643d95fab45299871840a50;p=deliverable%2Flinux.git

staging: vt6656: ETHbIsBufferCrc32Ok replace CRCdwGetCrc32

CRCdwGetCrc32 is a bitwise not of ether_crc_le.

Replace with ether_crc_le.
