[PATCH AUTOSEL 3.18 12/16] libata: whitelist all SAMSUNG MZ7KM* solid-state disks

[Sasha Levin]

From: Juha-Matti Tilli <juha-matti.tilli@iki.fi>

[ Upstream commit fd6f32f78645db32b6b95a42e45da2ddd6de0e67 ]

These devices support read zero after trim (RZAT), as they advertise to
the OS. However, the OS doesn't believe the SSDs unless they are
explicitly whitelisted.
