From 60e1b74c224e9eda14e5b479413c5d990373c2cb Mon Sep 17 00:00:00 2001 From: Nicolai Stange Date: Tue, 22 Mar 2016 13:12:45 +0100 Subject: [PATCH] lib/mpi: mpi_read_raw_from_sgl(): purge redundant clearing of nbits In mpi_read_raw_from_sgl(), unsigned nbits is calculated as follows: nbits = nbytes * 8; and redundantly cleared later on if nbytes == 0: if (nbytes > 0) ... else nbits = 0; Purge this redundant clearing for the sake of clarity.
