Subject: staging: vt6656: device.h Remove dead code bSoftwareGenCrcErr.
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4235f72fbcabebfeabb65cb7a740985337a1a1d4;p=openwrt%2Fstaging%2Fblogic.git

staging: vt6656: device.h Remove dead code bSoftwareGenCrcErr.

Probably an error in earlier firmware is never enabled so remove.

bPacketToWirelessUsb remove dead if/else and variables.
