Subject: [PATCH 3.16 194/305] libata: blacklist SAMSUNG MZ7TD256HAFV-000L9 SSD

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

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

From: Diego Viola <diego.viola@...il.com>

commit 410b5c7b48368317af95f0113692561d01d8144e upstream.

med_power_with_dipm still causes freezes after updating the firmware to
the latest version (DXT04L5Q).

Set model_rev to NULL and blacklist the device.
