This patch addresses the issue with ATA_CMD_SMART pio mode
command for enumeration and device detection with ATA devices.
The X-Gene AHCI controller has an errata in which it cannot clear
the BSY bit after the PIO setup FIS. The dma state machine enters
CMFatalErrorUpdate state and locks up. It is the same issue as
in the patch(Commit ID : 2a0bdff6b958d1b2523d2754b6cd5e0ea4053016).

Just "in the commit 2a0bdff6b958d1b2523d2754b6cd5e0ea4053016". And you also need to specify the commit's summary line in parens.
