[PATCH]: megaraid 2.20.4: Fixes a data corruption bug

[Bagalkote, Sreenivas]

Hello All,

Change Log:

Fixes a data corruption issue. Because of a typo in the driver, IO packets
were wrongly shared by the IOCTL path. This caused the whole IO command
to be replaced by an incoming IOCTL command.

This patch (generated against 2.6.9-rc2) is inlined below.
