Subject[PATCH] drivers/ata: correct a wrong free function for sata_nv driver
Date
From
For sata_nv driver in kernel 2.6.21 onward, Inside nv_init_one(),use
'hpriv = devm_kzalloc(&pdev->dev, sizeof(*hpriv), GFP_KERNEL);' but
using the kfree(hpriv) to free that data struction in nv_remove_one(),
which will cause system hang when removing the sata_nv module.

Change the 'kfree()' function to 'devm_kfree' will fix this bug.

The patch base on kernel 2.6.22-rc1.
