Subject: [PATCH] DMA: PL330: Remove unreachable code
Date: Tue, 13 Oct 2020 17:17:13 +0530	[thread overview]
Message-ID: <20201013114713.28754-1-surendran.k@samsung.com> (raw)
In-Reply-To: CGME20201013122030epcas5p2e576d5a2ebfaf9df8078e6ee70f3765c@epcas5p2.samsung.com

_setup_req(..) never returns negative value.
Hence the condition ret < 0 is never met
