From 8e71f694e0c819db39af2336f16eb9689f1ae53f Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Thu, 8 Oct 2020 10:52:04 +0100 Subject: IB/rdmavt: Fix sizeof mismatch An incorrect sizeof is being used, struct rvt_ibport ** is not correct, it should be struct rvt_ibport *. Note that since ** is the same size as * this is not causing any issues. Improve this fix by using sizeof(*rdi->ports) as this allows us to not even reference the type of the pointer. Also remove line breaks as the entire statement can fit on one line.
