Subject: IB/qib: Fix txselect regression
From: Mike Marciniszyn <mike.marciniszyn@xxxxxxxxx>
commit 2fadd83184d58701f1116ca578465b5a75f9417c upstream.
Commit 7fac33014f54("IB/qib: checkpatch fixes") was overzealous in
removing a simple_strtoul for a parse routine, setup_txselect(). That
routine is required to handle a multi-value string.
Unwind that aspect of the fix.
