[PATCH][V2] dmaengine: bcm-scm-raid: remove redundant null check on req

From: Colin King
Date: Wed May 17 2017 - 17:58:56 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Req is never null on at the point of the null check, so
remove this redundant check and just return &req->tx.

Detected by CoverityScan, CID#1436147 ("Logically dead code")
