3.5.7.32 -stable review patch. If anyone has any objections, please let me know.
------------------
From: "Denis V. Lunev" <den@xxxxxxxxxx>
commit efb9e0f4f43780f0ae0c6428d66bd03e805c7539 upstream.
Without the patch the kernel generates the following error.
ata11.15: SATA link up 1.5 Gbps (SStatus 113 SControl 310)
ata11.15: Port Multiplier vendor mismatch '0x197b' != '0x123'
ata11.15: PMP revalidation failed (errno=-19)
ata11.15: failed to recover PMP after 5 tries, giving up
This patch helps to bypass this error and the device becomes
functional.
