IB/qib: Fix txselect regression
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. Cc: <stable@vger.kernel.org> Signed-off-by: Mike Marciniszyn <mike.marciniszyn@intel.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
