Subject: staging/rdma/hfi1: Remove incorrect link credit check
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=bff14bb66c583376ff8c5dd6294796f6fc3c1dde;p=linux-beck.git

staging/rdma/hfi1: Remove incorrect link credit check

Remove an invalid sanity check that compares the local link
credits with the peer link credits.  The two have no dependency
on each other.
