From: Benjamin Romer Date: Thu, 23 Oct 2014 18:30:27 +0000 (-0400) Subject: staging: unisys: refactor CONTROLVM_PACKET_DEVICE_CREATE X-Git-Tag: v3.19-rc1~66^2~969 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f91b926273134d9bfec32d6c4fcbd5188afd07dc;p=karo-tx-linux.git staging: unisys: refactor CONTROLVM_PACKET_DEVICE_CREATE Get rid of the typedef for CONTROLVM_PACKET_DEVICE_CREATE, instead using struct controlvm_packet_device_create. Fix CamelCase names and update all references to changed names.
