The patch titled
ips: PCI API cleanups
has been removed from the -mm tree. Its filename was
ips-pci-api-cleanups.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: ips: PCI API cleanups
From: Jeff Garzik <[EMAIL PROTECTED]>
* pass Scsi_Host to ips_remove_device() via pci_set_drvdata(),
allowing us to eliminate the ips_ha[] search loop and call
ips_release() directly.
* call pci_{request,release}_regions() and eliminate individual
request/release_[mem_]region() calls
* call pci_disable_device(), paired with pci_enable_device()
* s/0/NULL/ in a few places
* check ioremap() return value
