Subject: libata: blacklist SAMSUNG MZ7TD256HAFV-000L9 SSD
From: Diego Viola <diego.viola@xxxxxxxxx>
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.
