Subject: [PATCH 4.2 188/258] ipr: Enable SIS pipe commands for SIS-32 devices.

4.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Gabriel Krisman Bertazi <krisman@...ux.vnet.ibm.com>

commit e35d7f27fbd51a09a41a5439e39f22a3d102c00b upstream.

Remove unnecessary check that disabled SIS pipe commands for SIS-32
devices.  This change was sufficient to enable raw mode and send SIS
pipe commands for a 57B3 device.

Fixes: f8ee25d7d239 ("ipr: AF DASD raw mode implementation in ipr driver")
