From: Colin Ian King colin.king@canonical.com
The variable 'data' is assigned null and never re-assigned. There is also a redundant check for data being non-null which is always false, so remove this and the variable data and dma_addr as they are not used once the dead code has been removed.
Detected with CoverityScan, CID#1324015 ("'Constant' variable gaurds dead code")
