[PATCH 35/39] dmaengine: ste_dma40_ll: Replace meaningless register set with comment

From: Lee Jones <hidden>
Date: 2013-05-15 09:54:59
Also in: linux-crypto, lkml
Subsystem: arm/nomadik/ux500 architectures, dma generic offload engine subsystem, the rest · Maintainers: Linus Walleij, Vinod Koul, Linus Torvalds

Unsure of the author's intentions, rather than just removing the nop,
we're replacing it with a comment containing the possible intention
of the statement OR:ing with 0.
