2.6.21-rc regression in mptbase

[Jan Engelhardt]

Hello world,


in at least 2.6.21-rc4, one or more of the mptscsi scsi modules is 
broken with respect to not detecting any harddisk (VMware provides that 
virtual LSI MPT controller), which means no working system.
No problems in 2.6.20.2.

I will be trying 2.6.21-rc1 shortly.
