Subject: [PATCH v2 1/2] IB/qib: remove superfluous fallthrough statements
Date:   Tue, 25 Aug 2020 18:12:42 +0100

Commit 36a8f01cd24b ("IB/qib: Add congestion control agent implementation")
erroneously marked a couple of switch cases as /* FALLTHROUGH */, which
were later converted to fallthrough statements by commit df561f6688fe
("treewide: Use fallthrough pseudo-keyword"). This triggered a Coverity
warning about unreachable code.

Remove the fallthrough statements.

Addresses-Coverity: ("Unreachable code")
Fixes: 36a8f01cd24b ("IB/qib: Add congestion control agent implementation")
