[SCSI] mpt fusion: Power Management fixes for MPT SAS PCI-E controllers
The system power state changes like hibernation and standby are not happening properly with 106XE controllers, this patch modifies the driver to free resources and allocate resources in power management entry points [jejb: compile fixes for upstream] Signed-off-by: Sathya Prakash <sathya.prakash@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
