3.2.75-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Mikulas Patocka <mpatocka@redhat.com>

commit d98f1cd0a3b70ea91f1dfda3ac36c3b2e1a4d5e2 upstream.

When I connect an Intel SSD to SATA SIL controller (PCI ID 1095:3114), any
TRIM command results in I/O errors being reported in the log. There is
other similar error reported with TRIM and the SIL controller:
https://bugs.centos.org/view.php?id=5880

Apparently the controller doesn't support TRIM commands. This patch
disables TRIM support on the SATA SIL controller.
