[PATCH] 3.19-rc7: add quirk for 1c28:0122 (rev 14) SATA controller

From: Tim Sander
Date: Mon Feb 02 2015 - 06:35:56 EST



The long name for this device is
Lite-On IT Corp. / Plextor M6e PCI Express SSD [Marvell 88SS9183] (rev 14)

Background: the error description on bugzilla
https://bugzilla.kernel.org/show_bug.cgi?id=42679
inspired me to check if my brand new m4 pci ssd could work with a quirk.
Its device representation is not visible before this patch.
After this patch it appears as a normal device. Formatting
and mounting worked so far.
